Dear

According to your information with a 68 percentile in JEE Mains under the general EWS category, getting admission to ECE (Electrical and Electronics Engineering) in top-tier government colleges might be challenging. The expected qualifying percentile for ECE in NITs and other government colleges is generally higher, around 85-90 for EWS category.

It's a good idea to confirm during counseling about the branch availability and cutoffs for your specific rank.

You might also want to consider other branches or colleges as a backup option from here College predictor

Thanks.
