With a CLAT score of around 74 marks, OBC category, and Bihar domicile, you do have a fair chance of getting admission to Chanakya National Law University (CNLU), Patna, but it cannot be considered fully guaranteed.

CNLU offers domicile-based reservation for Bihar candidates along with category reservation, which works in your favour. In previous years, the closing scores for OBC Bihar domicile candidates at CNLU have generally been lower than the All India OBC cut-offs. A score in the low to mid-70s has often remained competitive for state quota seats, especially by later rounds of counselling.

However, CLAT cut-offs vary every year depending on factors like the difficulty level of the paper, number of applicants, seat matrix, and counselling trends. If the paper is comparatively easier or competition is higher, cut-offs may rise slightly.

You should definitely participate in CLAT counselling and keep CNLU Patna high in your preference list. At the same time, it is advisable to also include other NLUs where OBC category cut-offs are slightly lower, so that you have backup options in later rounds.

Keep checking counselling updates and seat allotment rounds carefully, as many candidates get seats after withdrawals in subsequent rounds.

All the best.
