The best teacher i have ever studied from like i am blessed to be taught by him. Me being an introvert was afraid to ask questions but he helped me through it and i was able to ask as many questions as I wanted. I can say this with guarantee that if you have doubt you can ask this person a 1000 times and he will keep on explaining until and unless the doubt is solved . He helped me through tough times where no one believed in me he showed me the right path and guided along with it . At last i can say that this teacher is my key to success
