Hello Yash,

If the date has not been passed for application than you can get seat by applying in that college, note that you have to satisfy the eligibility criteria for that college.

So many private colleges are in India which take admission on the basis of JEE-Main score, like VIT Vellore, BITS Pilani, SRM University and many other. So you have to apply for that separately if they are not participating in JOSAA Counselling process.

I hope this information helps you.

For further queries feel free to ask in comment section.

Good Luck!!
