Heg !

The last year cutoff marks for OBC candidate for BHU UET was 147. So , if this year , to qualify for the exam ,you need a minimum score of 150 (to be on a safer side ). And since your score is more than 150 , then you qualify the exam.  And a score above 150 is enough for an OBC candidate to get a seat in DAV PG College. Rest , just wait for the cutiffs and hope for the best.

Best hopes!
