I have got 61 marks in JEE Mains. Can I get admission for engineering in NIT, Thadapalligudam?

Dear Pratyusha, Please use the link below to know the colleges you can get with this rank: https://www.shiksha.com/b-tech/resources/jee-mains-college-predictor In case you don't get a good college on the basis of this rank, then you can opt for some of the good private universities like LPU, SRM

No, you cannot get any NIT. You should try for any government. or private engineering college. There are many good private engineering colleges which provide good placements. Thank you.
