Dear Hafiz,

According, to students reviews etoos videos are good to prepare for your entrance exams.

It's depends on you now you want to prefer which way for your preparation. 

To score good marks in your exam it is very important that your concepts are clear. You should go through NCERT books to build your fundamentals strong. 

Solve mock test series as well for your practice and to analyze your preparation level at regular interval of time. 

Good Luck!!
