Hello Aspirant,

First of all don't set the target of marks in JEE-Advance instead you should set the percentage goal for JEE-Advance like  for good IITs if you belongs to General category then the percentage you should aim for is around 50% in JEE-Advance, the reason being, there is no any fixed marks pattern for JEE-Advance it can either be of total 360 marks or it can also be of 720 or of any figure.

I am enlisting down some tips for preparation of JEE-Advance which would help you in achieving your goal upto some extent :-

** Make a proper time-table to balance your studies and daily routine work (like your hobbies, refreshing your mind and so on)  and give little more time to studies and also in studies make a timeline for each three subjects.

** In last 2-3 months you should primarily focus on solving papers as you have completed your preparation of JEE-Main so you will have some ease for preparation of JEE-Advance.
