Hello Aspirant,

If you want to get more than 480+ marks the only thing you want to do is keep more concentration on lectures and practice on daily bias. Make sure that you are clear on particular topic, if you have any drought clarify that.

Mathematics: You need to do more and more practice both the papers 1 & 2. Firstly be aware of formulas, theorems  and make a note of them so that you can refer them at the time of examination. Practice as much as you can this will improve your speed.

Physics & Chemistry: Be aware of all the chapters and go through equations and structures and chemistry. In physics note down the formulas and prepare on study material provided by your college.

Sanskrit & English: Spend at least 8-10 days of time on Sanskrit to prepare it will give you good marks. Coming to English this is the most easiest  subject but not neglect. Go through grammar part  more.

Practical's: Do practice all the experiments in the lab. So you can easily get 60 marks. And participate well in viva.

And finally at the time of your examination go through important questions(blue print). You will easily get 480+ marks.

Hope this helps you.

All the Best!!!
