First of all, read the NCERT books properly. Knowing this content itself is enough for you to score great in Mains and decently in Advanced.
Solve as many problems as possible. Repeating same problems is no problem; infact, it is good to brush up what you have practiced previously.
Just remember the exception and note them as many exceptions as possible in a notebook and revise the on the last month before exams.

FIITJEE AITs has tough question, most of which are beyond JEE level i.e irodov has toughest question in physics.
For maths, solve S.L Loney and I.A Maron.
For chemistry, there is no particular tough question, instead exceptions are there. So, learn them without mixing with concept.

Depends on what NIT you have a chance of getting in. If there's any possibility that you'd be getting a branch of your choice in NITT, NITK, NITW, NITC or VNIT, then you can go ahead with that. Otherwise, I'd suggest you to go for Long term coaching and try the best you can to get into one of the older IITs. All the best :)

Hello,
Greetings from Shiksha.
Well, the marks you scored says that you can't get IIT directly you have to do long term which will grab your talent and you can end up in IITS.Better approach a better institute and keep focused.
All the best.

You are not eligible for JEE Advanced as you require minimum 75% for getting admission in IITs and NITs. You need to prepare very hard for JEE Mains as it is the only way for you to get admission in the best colleges of India. Good luck.

Complete NCERT more than twice and be thorough with the concepts. Once you are done with this then complete the solved problems, go for Arihant's text series, buy them as this will help you a lot.
Good luck.

Varanasi has many good coaching centers for entrance examination. I will suggest you to join JRS tutorials. You have be determined and focused to clear JEE with a good rank. All the best.

If you are determined enough to crack JEE or you think that you will crack it the go for it otherwise you should settle with the available options. One year is very important in life. You will realize this later.
