JEE Main || Physics Important Topics || Improve your Ranking with this artical

Are you 12th passed? and preparing for  JEE ( Joint Entrance Exam) Main so this post is for you. JEE Main exam is must required for engineering, So how to prepare or what should I read for JEE main,

JEE questions are related to 12th and your little preparations can help you get good marks in JEE exam.

First, learn about subject that related to JEE and policies of JEE exams, the number of total questions in JEE main are 90 and each question of 4 marks, so Total marks = 360 

For every wrong question, your marks will be reduced, so be careful of every question.
