Hello vinod,

Assuming this is your percentile of JEE mains paper 2. The only thing you can do is study HARD. 

If you make a proper time and follow it strictly you can score a descent score in JEE. If you are not loyal towards yourself, then clearing any exam will be very tough.

Just stay motivated, be loyal and strict and follow your time table. At the end of the day do check your progress and when you will see that progress bar rising you surely will feel the positive vibes in yourself and i believe you will come up with flying colors.

All the best.

Hello.

The official rank list will be released by NTA after the completion of the exam in April. Your predicted rank is about 7.9 lakh, this score is neither sufficient to qualify for Jee Advanced nor to get admission into NITs. You could reappear for the second session of the exam and try to improve your score.

Good luck!
