I have more than 7 years of tutoring experience.
I have taught more than 10 students over the past years and they have all completed their O level's.
I taught most of them when they were in Primary school, whereby I prepared them for their PSLE, and all the way to when they sat for their O level's.
Most of the students I taught scored well for their O level E maths, Science (Phy/Chem) and Chinese. Most managed to score at least an A2 for all the 3 subjects.
