I get 40 marks in pg physics paper of cucet . Can I get a chance in curaj or cuk or cupun?
You didn't mentioned your category. Assuming you are a General candidate , I am giving the answer.
Your score isn't bad. But getting a seat depends on the rank and the cut off percentile. So its predicted that the cut off for CUCET colleges like Rajasthan , Haryana , Punjab etc will be under a score of 38 (approximately). So by that prediction , you have a fair possibility of clearing the cut off but getting a seat is to be decided by the corresponding.
