I tutor Chemistry, Physics and Biology, as well as A/Emath on the sidelines. Will attend to questions on these subjects, time permitting. Little or no time during the exam period, as I will be busy working to prepare my students to score well.

Get expert help for Emath, Amath, Physics and Chemistry at Eton Tuition Centre (next to Hougang Mall). Tel: 63853133 A friends Centre, where I tutor O-level Chemistry.
