Dear aspirant,

To be honest , jee mains is such a examination which you cannot ace it overnight . You need focus , dedication, hardwork with smartwork for a couple of years atleast .

You can barely think atleast clearing the cut off considering you are starting from scratch.  So, i would advise to practice mock papers as much as possible after your preparation because these are the key factors to score good in the examination.

Focus on your strong points rather than weak ones as there is no time for it. So, kindly practice the previous years too before the examination.
