jee main me 71percentile h nit, iiits, and GFITs me admission mel sakta h. uske leye kese counselling karwana parega.

Hello,

Since you have not stated which category or state you belong to I'm gonna answer this on a general perspective.
Getting into IITs, NITs or GFTIs might not be possible for you if you're a general category student with a 71 percentile in JEE Mains, although you can still try for state counseling like Haryana, MP, Odisha etc.
You'll be eligible for private universities/colleges.
To know your admission chances in JOSSA & State counseling you can use JEE Main college Predictor tool.
