Mole Calculations is considered the No. 1 Killer Topic for GCE ‘O’ Levels / IGCSE / IB / IP Chemistry by students as well as educators (teachers, tutors) alike. Many students cannot understand how Mathematical Calculations are being combined with abstract Chemistry Concepts, not to mention to score in examinations & tests with questions related to Mole Calculations.
“Before I came to this Mole Calculations Mastery 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!”

Mole Calculations, also known to many as Mole Concepts, Stoichiometry or Chemical Calculations has been voted by year-after-year, batch-after-batch, as one of the reasons why they can’t score in Chemistry Examinations. This topic is covered as early as Sec 3 and is tested in both Sec 3 End-Of-Year Chemistry Examinations as well as GCE ‘O’ Levels / IGCSE / IB / IP Chemistry Examinations.
There is NO WAY you can neglect this topic (don’t even dream of giving up this topic!) because they are usually found combined with other topics in a question i.e. you can’t run away for it. They are highly application and there are no way you can memorise it. The only way to score is to understand the essential concepts involve and having the correct strategies to work out the correct answers.

“Just like my previous experience with the Organic Chemistry Mastery 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!”

“I’ve gained a lot from this workshop, and in 8 hrs I’ve learnt so much more, as compared to learning it for 2 months or so in learning centers elsewhere. The step-by-step explanations really aided me in my answering techniques, and because of this I will be able to apply it in my work. And, I think I have started to like Chemistry already! =)”
Sivhanyaa, Paya Lebar Methodist Girl’s School (PLMGS) 2008
“I understand more in Mole Concepts now! It has helped me greatly, in clearing all my doubts on Mole Concepts. The notes are all helpful and much clearer than those my teacher gave. Sean has gone through, guide through the various steps in answering Mole Concepts’ questions.”
Sheryl Lim, Queensway Sec School 2008
“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.”
