Hi there,
Hope you are doing well.
70284 rank is very high in case of JEE Mains paper 2.
Unfortunately, you won't be able to get into any of NITs or GFTIs or SPAs since most of them have a closing rank of at most 7,000-8,000 for General Category, but you can try for private colleges.
Hope it would help.
Thank You.
