JEE Main results are given in percentile, not percentage. If you mean 67 percentile, then getting admission in top NITs, IIITs, or GFTIs is difficult, especially for General category students. However, if you belong to a reserved category (SC, ST, OBC, or EWS), you might still get a seat in some lower-ranked colleges or branches. Also, many good state or private colleges accept low JEE scores. Apply through state counseling and keep backup options ready. Don't give up!
