I haven't fill it for up round one and I will fill for round 2 my rank was 3.3 lakh and round one cut of TMU BDS is 5 lakh something so are there any chances I can get in round 2

Yes, you can still have a chance in Round 2 if you are eligible to participate in the counselling and seats are available.

A rank of 3.3 lakh is better than a Round 1 closing rank of around 5 lakh, so based purely on the previous closing rank, your position appears favourable. However, the Round 2 cutoff can move in either direction depending on the number of candidates participating, seat vacancies and choice preferences.

Since you did not participate in Round 1, make sure you complete the Round 2 registration/choice-filling process within the prescribed deadline. Fill the desired college and course in your preferences and include some backup options as well.
