Instead of joining any coaching classes, you should go for smart learning
And I would rate smart learning method 10/10
See, coaching classes are just the means of wasting your time and money as their motive is just to make profit out of their business
So, in this regard I would suggest you “M-learning India”. It is the best app for self study
Download “M-learning video streaming app” which would help you get access to hours and hours of videos with offline streaming and download facility
Moreover, an app based learning would be beneficial today
Through M-learning, you would get each and everything at your finger tips
Watch “M-learning video lectures” for 2–3 hours and try to solve questions for 3–4 hours regularly
Also it provides you “M-learning course details” for further reference
And its doubt clearing session would help you clear all your doubts
