Hi aspirant

If you have scored 75%ile and you are general then you haven't scored enough to get NITs/IIITs and GFTIs .So you can try for state engineering colleges.You must be knowing form this year onwards almost all state engineering college will take admission on the basis of JEE mains marks .

You can apply in state counselling or if you have appeared in BITSAT,VITEEE,SRMJEE,Manipal,GITAM or any other entrances then you can take college on the basis of these entrances.
