Dear Aspirant,

Increasing a lot of marks in a short period of time is hard but there are a few tips that'll help you at this time.

1. Focus on inorganic chemistry, memorize the ncert part of it thoroughly.

2. Learn statistics, environmental chemistry, communication systems well.

These topics are easy score in JEE exam.

3. Don't learn any new topics at this moment just revise all your concepts and write as many mock as possible. While writing exam, optimize your time really well. Make sure you clearly know which questions bro attempt and which ones to skip, take 5 minutes in the beginning for that. A lot of success in Jee can be attributed to good time management, so make a strategy and practice that using mock tests. Don't forget to solve previous year questions, understand the concepts of those questions really well.

Hope this helps.
