Hello. Dont worry, just keep on studing and give mock tests. This will help you understand your in depths clearly. And then attend for jee main 2021.

If you practise rigorously and show full dedication, then definitely you will get NIT .

Already you have got a drop , so if you are confident that you will perform very well next year in mains, and will get into NIT, then give time to yourself and prepare well.

All the best!

Hoep that helps!
