O Level Chemistry – Periodic Table Mini Series (Part I)

Hi everyone,

It is a brand new year and we will continue where we left off last year, on sharing more:

  • Chemistry Phenomenons (show how abstract chemistry concepts are linked to our everyday life)
  • Chemistry Tips (simplify chemistry theories in bit-size, concise points for easier understanding)
  • Chemistry Strategies (discussion on exam-based tough questions and the strategy to answer it)

For the last two fridays, i was focused on coaching a group of committed Sec 4 students (under the Chemistry Ultimate Leap Programme 09) on the topic of Periodic Table & Trends.

(Chemistry Coaching in one of our training rooms)

Majority of the students have gone through this topic in their schools before, and found it lame redundant for us to talk about it. From their expressions, indirectly it signals to me that i should be coaching them on other topics instead.

I am glad i held my fort (and i always do! ) and continue with the topic, because i realized that their understanding of the topic is not anywhere strong enough, to handle GCE O Level Exam Questions (this is clearly the case based on their scores/marks in their PreReview Tests, before i formally start the academic coaching session).

Now, let’s get this straight..when we mention Periodic Table, it is the “Bible” of Chemistry. You need to know the following well:

  1. Features of the Periodic Table
  2. Trends in the Periodic Table
  3. Group I elements’ Properties (Physical/Chemical) & Trends (down the group)
  4. Group VII elements’ Properties (Physical/Chemical) & Trends (down the group)
  5. Group O elements’ Properties (Physical/Chemical) & Trends (down the group)
  6. Transition Metals’ Properties (Physical/Chemical)

Comprehensive understanding of the above is crucial, as Periodic Table are usually linked to other topics, and there is no way a chemistry students can run away from it.

In fact, i expect GCE O Level students to score high FULL marks for any questions related to Periodic Table. This is a basic chapter and you need to score well here, in order to do well overall in Chemistry Exams.

Starting with this blogpost, i will be sharing & discussing tricky exam-based questions on Periodic Table & the strategies to work out the correct answers – through Periodic Table Mini Series (series of blogposts)

Let’s check out a couple of exam-based questions related to Periodic Table:

Question 1:
Boron and aluminium are both in Group III of the Periodic Table.
Which statement is true for these two elements?
a. Both elements are metals
b. Both elements contain 3 electrons in their outermost shells
c. Both elements form acidic oxides
d. Both elements have the same proton number

Question 2:
Silver (Ag) resembles Group I elements in some properties.
Which property of silver is NOT typical of Group I?
a. Silver atoms have one outermost shell electron
b. Silver forms a chloride with formula, AgCl
c. Silver conducts electricity
d. Silver is resistant to corrosion by steam

PS: Do your best to work out your answers! I will share my suggested answers + explanations, when i see people participating (cos learning can only be effective when you participate 100%).

PPS: You can write your (suggested answers + explanations) in the “LEAVE A REPLY” section right below this post.

Stay tuned to next blogpost on Periodic Table Mini Series, where i will share more Chemistry Tips & Strategies on Periodic Table, and discussed more tricky exam-based questions. For now, you can check out the ARCHIVES (previous blogposts discussions) on Periodic Table HERE

Until next post, take care!

O-Level Chemistry Examination: What is it actually?

Many of you (Sec 4 and 5) would be taking the GCE O-Level Chemistry Examination this Oct 2009. In your school, your teachers should have gone through 3/5 of the Chemistry Syllabus by now. What you are going to experience next is a fast-pace, adrenaline rushing “chapters-crunching” within the next 3 months, whereby your school teacher will try to finish the rest of the 2/5 syllabus, in order to welcome the Mid-Year Examinations (this exam will show you how much you understand what has been taught for last 2 years).

For those in Sec 3 (2009), you should be studying the chapter on Methods of Purification, Solids/Liquids/Gases or Elements, Compounds & Mixtures,etc. Many of you might wonder what you are studying – some will be “blur like sotong” (in dialect it means “Really Lost”). Many question marks around ???

The basic question many of you would ask me is:

“What really is O-Level Chemistry Examinations?”

“How to Do Well in O-Level Chemistry Examinations?”

My answer to you will be:

It is just a GAME! And in games, you will need to understand the Rules & Regulations (even before you learn the techniques & tactics) in order to do score well within a Time-Period . Sounds like Soccer, Rugby, Baseball, Basketball competitions? Yes..you can equate Sports Competition = GCE O-Level Examinations.

Before we learn the game, the coach will always brief us on the Rules & Regulations, before he steps on his gear to coach you on the Techniques & Tactics.

In O-Level Chemistry Examination, we would first need to know the Rules & Regulations Scheme of Assessments / Arrangement of Chemistry Examination Papers and the time period allowed.

The O-Level Chemistry examination consists of two theory papers and one practical paper:


(click image to see clearly)

Paper 1 consists of 40 compulsory multiple choice questions. Each question carries 1 mark.

Paper 2 consists of two sections:

Section A carries 50 marks and consists of several compulsory structured questions.

Section B carries 30 marks and consists of three questions:

- The 1st two questions are compulsory and have total weightage of 20 marks

- The 3rd question gives you a choice from two questions and carries 10 marks.

Paper 3 is the School-Based Science Practical Assessement (SPA) which involves a set of school-teacher-assessed practicals spread over the two years of your O-Level course.

Note: The marks for each papers are not simply added up. They are weighted (or scaled) to the percentages shown in the table shown above. E.g. the Multiple Choice Paper (Paper 1) is marked out of 40 but contributed 30% of your final O-Level mark.

PS: The above table and discussion is based on Pure Chemistry Syllabus Exam Code 5066. Some students are taking Pure Chemistry Syllabus with other Exam Codes such as 5067, 5068 & 5072. Others may be taking Combine Science (with either Biology or Physics) and have Exam Code such as 5116, 5118, 5152 & 5154). You can check out the Singapore Examinations & Assessment Board (SEAB) website for more specifics, but what’s important is to know the Scheme of Assessment while you prepare for exams.

With these Rules & Regulations of O-Level Chemistry Examination in mind, i will continue with Year 2009 to provide O-Level students with more Chemistry Phenomenons, Tips & Strategies so that you can achieve the score that you truly desire.

2009 GCE O Levels Chemistry – How to Choose An Effective Tuition or Tutor

With the release of the 2008 GCE O Level Results 2 days ago, now the focus is back to the current crop of students taking their 2009 GCE O Level Examinations in 9 mths time.

Over the last 2 weeks, i have seen a surge in phonecalls and email enquiries about Chemistry Coaching by parents for their child. Many parents have confided with us on the difficulties in getting their child to Revise Regularly and having the correct mindset of Consistent Hardwork, in order to be more relax when O Levels are nearing. Many of parents are also searching for Tutors and Tuition programs to help their child to build up a strong foundation of essential concepts.

This bring me to blog aboutHow to Choose An Effective Tuition or Tutor“. In fact, i had made a similar post in Dec 2007 after numerous enquiry by parents on Chemistry Tuition / Coaching.

In the following, i will add on what i have discussed before on Choosing An Effective Chemistry Tutor/Coach:

1) Chemistry Competency & Life Experience

An effective tutor should possess mastery of the Chemistry Subject he is teaching to ensure that he is imparting the correct knowledge and skills to the students. For chemistry, it is even more important that any other subjects, as many students viewed Chemistry as “LAME”, “BORING”, “ABSTRACT CHEMISTRY THEORIES”, “NEED MEMORISE ALOT”, “I DONT SEEMS TO UNDERSTAND HOW CHEMISTRY THEORIES WORKS”, “I CANT SEE HOW CHEMISTRY IS USED IN EVERYDAY LIFE”, etc..

The tutor coach would be most effective if he personally have Chemistry Research or Industrial experience, so that he can translate those “abstract Chemistry Theories” into “Interesting Everyday Life occurences”. This will certainly help to increase the interest of the child which will lead to scoring academically in GCE O Level Chemistry Exams, as the child are highly motivated and intrigued to find out how each and every chemistry theories are related to things around him.

2) Coaching Experience/Credentials

Who can teach your child? EVERYONE ! Yes. Everyone that has finished GCE O Levels will claimed they can tutor your child – just because they have went through the exam before, and especially if they scored an Ace for it? But the question is, does it mean that scholars definitely are able to teach?? Not necesaary! Being A Teacher is different from being A Student. Scholars does not necessary mean that they can effectively coach your child towards academic excellence. This is contrary to many parents’ belief. (no prejudice against scholars =) .hee..i did pretty well also during school days..)

In fact, what parents should be looking at should be the Coaching Credentials / Experiences that the tutor have. Testimonials by ex-students and parents should be a good gauge if the tutor are able to assist your child.

3) Dedication & Commitment

A good tutor coach shows Dedication & Commitment in his teaching and is always willing to go the extra mile to help the students realise their maximum potential and improve their studies, by utilizing their resources and experiences.

Many a times, we have seen Part-time tutors and/or even School-Teachers (that are earning extra buck over the weekend..hmmm…does MOE knows about it i wonder?) more interested in getting a fatter pay check each month, rather then focusing what’s on their plate and doing their role well. They take up more assignments from Tuition Centres & Agencies (which are run by Businessmen) that calls them up. Unfortunately, you will only realise this only after a few sessions with the tutor. As such, you need to check with your child after each lesson what he/she has learned.

4) Open Communication

What beats open communication between the tutors and the parents (and students)? Students learned best when their teachers and/or tutors give them feedback on their progress and highlights their areas of improvements so that they are able to work on what they are not so strong in.

But we realise that many tuition centres do not have this in placed. What happened is that Tuition Centres are usually run by businessman and their main aim is to stay as profitable as possible. The person tutoring are in fact out-sourced (school teachers, undergraduates, housewife, etc) and paid on a per-lesson rate. In this case, how can you expect to have communication??

In our coaching, we highly emphasized on open communications and feedback from students and parents. We always pay attention (on individual basis even though our coaching is in seminar settings) and listen to their learning difficulties and work out strategies to help them improve their understandings.

Besides that, we also have “observers” when our Master Trainers are coaching, so that these “observers” can feedback to the trainers on their performance, and the trainers can make improvements in the next session. In this way, our coaching methodologies can only get better and better.

5) High Energy Coaching

The tutor coach must be able to deliver the learning materials and concepts in an appealing way and engages his students actively in lessons, making learning a natural and constructuve process. Only this way, students become interested in the subject and also become motivated to work hard.

In physics, we call this CONSERVATION OF ENERGY – everything in this universe is about energy, and energy is never lost, it is only transfered from one form to another form. Only when the coach has high energy in coaching, will the student have the energy to learn effectively and efficiently. In our coaching methodologies, we call it Accelerated Learning Techniques! Energy allow students to learn faster and better.

6) Good Class Management

It is important that the whole class / group are happy when they are learning. It is not just the design of the classroom that needs to be conducive, but the tutor coach must be able to have Good Class Management for effective learning. This will help the students to feel at ease and confident of themselves so that they are able to absorb the knowledge.

7) Encourage Questions To Be Asked

HAHA. Many tutors and teachers HATES THIS!   QUESTIONING from students.

I think it is because they did not learn the skills of proper managing a class / group. So whenever a students asks a question, they feel as if the students are purposely interrupting his teaching. Many are also afraid that they may not know the answers to the student’s question.

Isn’t it ironic? We have been taught since young, that Question Are Never Dumb! We also know that many great scientists and inventors are what they are known now, because of the numerous questions that they asked themselves. So by blocking questions by students, we are indirectly blocking them to maximise their potentials.

Questions MUST be asked. And if the teacher/tutor are not able to answer the questions, what they can do is to truthfully acknowledge it, that it is out of syllabus, but for benefits of knowledge, the teacher will check and tell them the next lesson. The students will be more than happy to wait for the answer. =)

I hope the above helps you (parents) to choose an effective tutor or tuition centre.

Options Available – After getting your GCE O Level results

AFTER TAKING YOUR GCE O LEVEL RESULTS – WHAT’S NEXT!

Yesterday was all the tears of joy for most when your obtained your GCE O Level results. It was the time for recognition of all your hard work and positive attitude towards the preparation of this major examination for the last 4-5 years in secondary school. If you have scored an A1/A2 for your Chemistry – it must have to do with the strong foundation that you have built on the essential chemistry concepts, fortified by the Consistent Hard Work and Regular Revisions. Congrats!

Just like LEFT & RIGHT, BACK & FRONT, EAST & WEST, there are students that fared very well and have lots of joy, but there will also be some that have not done so well in this examinations. No matter which group you belong too – i must add that you still have a long road ahead of you =). Stay always Positive and remember there are many options that are available to you after your O Levels. Most important is to consider your aptitude and interests carefully before making a choice.

O Level students these days have more choices and flexibility than ever. More JCs are offering both science and arts subjects together to cater to students with varied interests while polytechnics are introducing new courses to meet the demand for qualified workers in growing, multi-million dollar industries such as digital media and biomedical science industries. The Open-House for the 5 Polytechnics have passed but i believed you still can find out about the course details at their homepage. Check out my earlier post.

The Institute of Technical Education (ITE) is also expanding its range of courses. You can check out the available courses HERE.

There is also many direct universities route such as SIM that allows O-Level graduates to obtain certain degress in just three years, not to mention the many Private Schools that are offering Diplomas in different areas. Note: For Private Schools – there have been recent commotions about their credibility. My advice is to check them out carefully and ask for prove of their accreditation, if necessary.

For those that are more inclined towards ARTs, you can also consider Nanyang Academy of Fine Arts (NAFA) as well as LaSalle College of the Arts, which are having their Open House this weekend.
So with choices galore, how should students decide where to go after the O’s?
Just a year ago about the same period, i made a blogpost on “Options Galore! Choosing the Right Path for O Level Holders!” Check out this interesting post HERE if you are undecided what to do next.

Hope this post is helpful to you.

PS: Drop me a comment as i would love to hear from you. =-)

2008 GCE “O” LEVEL TOP STUDENT – What’s the Secret!?

2008 GCE O-Levels topped by a CHIJ girl

Congratulations to all that have done well!

WHAT IS HER SECRET of Acing THE 2008 GCE O-LEVELS???

CONSISTENT HARD WORK & REGULAR REVISION !” she says

I have always been emphasizing this point to students under my coaching (as well as their parents) that there is no such thing as “Miracle” or “Short-Cut” in academia, especially when it comes to Chemistry which requires you to understand the Essential Concepts before you can use it to solve Application Questions.

Of course, i have empowered many students to score well and improved in very short-time period through my different coaching programmes. But i must make clear that it is the student that put in 110% focused and efforts that made it possible for themselves. They have put in many nights and days of Hard Work to compensate for the lack of consistency and regular revision.

But to Top a cohort in exams, you would need to have Regular Revision & Consistent Hard Work! It is also crucial to review your past test and exam papers, especially those that you have got it wrong before-bcos there is a 80% tendency that you are going to repeat the same errors/mistakes again. Up Your Chemistry Grades Now! chemistry book that was written by me in August 2008 aims to help students in this area…that many students have neglected. She understand this point clearly since the start.

For those reading this blog and going to take the GCE O Levels in 9 months time, it is time to start WORKING HARD & REVISING REGULARLY!

You could be the TOP STUDENT FOR 2009!
