Hello,

First of all, don't get demotivated . You still have 3 months, you can give your best and try to qualify for JEE Advanced . You should study according to your self made time table and revise each topic thoroughly . Give as much as mock test you can give .

Basically , what happens in mock tests , you opt for many questions and you think you can answer each and every question. But in JEE Main , you should only answer those question which you think will be right.

You can give mock test and practice using the below link :
