Hii..

Firstly focus on the basics of class 11th & 12th,then try to solve the previous year question papers as well as mock test series.I am sure this will be helpful to you.

Thanks..!!

yes off course it's a very common strategy, to sum up your preparation or you can say that the final touch to your syllabus.

one must always try to solve the mock papers followed by the correct and precise analysis of the strong points and the weak points.

don't linger much upon the complex questions try to sharpen your strong point as much as possible it also helps you revise the important topics in accordance with the practice too.

all the best !!!!!
