JEE Main

You can't get NIT college with 62 marks. You can try for autonomous colleges and top private colleges.

You can get semi-government or private college only not the best college. For best engineering college, you have to come rank under 10,000 rank or 30,000 rank. So, if you want to try for good marks prepare one year and apply JEE Mains next year.

Your JEE Mains marks is some short but as you said, you are from SC category, you can get a good government or semi government college. If not, then top private college will you get and scholarship from government. Also, I'd provide you the burden of fee will reduce.
