Study is not hard as subject is not hard to study, depends on the teacher who teaches you that subject. This is Dr. Gaurav dynamic at teaching won't let you hate the subject or the process.

So, Gaurav Sir is one of the finest teachers I have ever met. The key feature of Sir's teaching is that Sir explains the concept without any rattafication.
These concepts will last longer in ur mind ... The revision strategy of Sir is also fantastic.
Sir takes multiple revisions. Just at the time of teaching only.
With the Sir's guidance, anyone can crack any exam. Thank you, Sir
