Hello Ayush,

We cannot specify the exact number of marks in the JEE Advance for you to get into the core branches in the top IITs because even the total marks i.e the maximum marks in the JEE Advance is also not fixed and it changes every year.But your rank I'm the JEE advance should be less than 2000 for you to get the admission into the branches which you have specified according to the previous year closing ranks.
