Why Mole Calculations Revision Workshop?

Mole Calculations also known as Mole Concepts is the #1 Chemistry Killer Topic for many students based on my 15 years of Chemistry coaching.

In Chemistry, Mole Calculations is a very important component: it is the topic which is always integrated with almost every Chemistry topics as observed in past few years of GCE O-Level Examination Papers. In fact, Mole Calculations will be tested in every Chemistry Examinations. Can your child afford not to be a master in this topic? Just like Calculus is the language for Mathematics, Mole Calculations is the heartbeat for Chemistry. Imagine how your child's state of mind will be affected when they cannot handle the Mole Calculations questions in their O-Level while their peers are cruising through the papers, just because they knew the strategies to solve the questions!

Does your child face challenges in the #1 Chemistry Killer Topic - Mole Calculations?

If your child is confused about Mole Calculations and doesn't know how to apply what was taught by their school teachers or personal home tutor, here's the solution: Learn how to go from clueless in Mole Calculations to understanding the concepts and the strategies to apply in real examination questions.

Stop struggling and start succeeding! Learn from me who can show your child the step-by-step on how to master Mole Calculations in 3 days!

Calculation of % Yield & % Purity from relevant data


 Here's what past participants say about Mole Calculations Revision Workshop:
"This programme has allowed me to clarify many of my doubts about Mole Calculations and served to boost my confidence in tackling such problem sums in Chemistry. It is different in that it focuses only on Mole Concepts & Calculations, and as such resolves the issues I have with this topic effectively. I would of course recommend it to anyone that is unsure of coping with Mole Calculations."
Marylyn Tan, Singapore Chinese Girls' School


"Before I came to this Mole Calculations Revision Workshop, I thought it would be intensive and tiring. After it all, I felt that as if time passes very quickly. This is because, I am learning. When one is engrossed in doing what he or she is doing, time would seems to fly. The food and the environment is great! I am sure the following workshops would have the same standard and even get better and better. Flip-charts and motivational slogans are helpful in perking me up. MOLE ROCKS!"
Marcus Goh Kang Rong, Queensway Secondary School


"The workshop is very engaging and it helps me gain interest for Chemistry. I have a better understanding towards Mole Concepts now and is able to work on a lot of questions that were never possible for me to solve before. The lessons are very clear and detailed, and I would definitely recommend this workshop to my friends who are weak in Chemistry as it has successfully built up my fundamentals for Chemistry."
Lovin See, CHIJ St. Nicholas Girls School


"Just like my previous experience with the Organic Chemistry Revision Workshop, Sean has a very different and unique approach in ensuring that his students would fully understand everything that he taught. His method of teaching is truly remarkable and amazing as he managed to make me, who have absolutely no interest and understanding of Chemistry, clear my doubts and removing my hatred for Chemistry. Thanks a lot Sean!"
Chua Tok Sheng, Bedok South Secondary School


"It helped me see an overview of Mole Concepts clearly in a short timing of 8 hrs. I think that the Flip-charts on the wall are very useful in helping me to memorize the concepts. Overall, I think the Mole Calculations Revision Workshop is great!"
Serena Chia, Pasir Ris Secondary School


"It helped me to understand better the concepts of Mole Concepts & Chemical Calculations. I learnt how to solve the questions using a faster and more effective way. Now, I won't make so many mistakes when I do questions on this topic. Very effective since the workshop size is small. Mole Concepts & Chemical Calculations are actually not tough, as long as you understand the concepts & strategies well. Recommend it to friends."
Anthea Zee, Holy Innocent's High School

Hi Sean, just want to say a BEEG thank you being an inspiring teacher. Your passion for Chemistry & dedication in teaching are a great motivation & inspiration to your students. You do not choose only the 'A' grade students but inspire them to be. Because of your help, Tim (Timothy) improved his Chemistry and was able to spend more time brushing up other subjects. Thanks! Rgds, Mrs Ho"

Hi Sean. Would like to share about Zamann''s results. He got a B3 for Chemistry. Thank you very much for your guidance. From Mid-Year (F9) to Prelims (C5) to B3 (O  Level s ) in just 3 months! Without your guidance, he will not be where he is now. He is eligible for JC and Poly. I sure will recommend you & Winners Education Group to others! =)"
