Well, I am really new to tutoring but I truly believe a good student can be a better teacher. I have always been a topper at school. I passed my Chartered Accountancy at a very young age of 23, a rare feat for most of the students. I am really dedicated to whatever work I do and I am very strict regarding deadlines. i am always committed and dedicated to whatever work allotted to me and I make sure it is completed well within deadline and also I try to give my best in whatever I do. Hope we will have a good time studying together.
