You can form a group with your friend for group tuition for maths and Chemistry, from secondary A/E maths and chemistry till A level maths and Chemistry. Or one to one tuition at your preferred place. I am NUS Ph.D in chemistry and have 20 years tuition experience in Singapore. Also provide CIE syllabus tuition for chemistry. One of my students got good results and went to Cambridge University this year. Hope you or your child also can. Able to arrange chemistry practical sessions for those students who are taking CIE exam or as private candidates who takes A level exam but don't know where to find the lab. I can help you with this (fees applicable).
