Hi, 

A very important advice which I want to give is that don't get confused regarding different study material. There is lot of traffic when it comes to choosing study material. If you are studying in any coaching, go through that syllabus properly. Your focus should be on NCERT. Clear your concepts there and then go to different books for MCQS. solve as many mcqs as you can. Just don't get confused and keep one track focus. 

Good luck!
