Thanks for A2A,
This is above average marks and by this marks you can get a rank 1.5k-2k which also depends on toughness of paper.
For this marks …you should have to learn all the basic formulas of Physics,chemistry and maths.Learn name reactions of chemistry.Don’t forget to revise the topics of thermodynamics of physics and chemistry .
In mechanics section you can easily score and If your maths is strong then I do believe you can get more than 50/60 only in maths. In chemistry part many students does not give attention to S,p,d and f block elements and lose marks. I hope you will not do this mistake. Inorganic chemistry is the easiest part do practice by Balaji publication books and your coaching study materials that’s enough.
The things which matters in this exam is speed and accuracy. You have to practice hard.
