As I'm a Ph.D. student, so I'm more focussed on my chemistry laboratory. I have qualified two national level exams viz, GATE, and NET JRF (Rank 68). So I'm highly qualified in chemistry subject. Also, I have two years of teaching experience in this subject, which includes college teacher as well as a personal tutor. I can assure you if you hire me on this particular subject, you are never going to regret it.
Best Regards.
