Professional All Subject Tutor Online and Offline

I have been tutoring for about three years now. My primary subject is chemistry that I teach to higher level, although coming from a hard core science background I have good grasp of Physics, Biology and additionally of Mathematics as well for lower classes.
It's hard to find a tutor these who have a good knowledge of all the subjects.
Although its up to the student what they want to learn from me, I believe I would be ideal for students within the age group from primary to IGSE level.
I have completed my Bachelors of Science (Honours) in Biochemistry. Currently I am pursuing M.Sc in Biotechnology and Enterprise.
