Is there any sectional cut off to take admission ?

Dear Lopa, by sectional cut off, if you mean minimum marks to score in each section of Physics, Chemistry and Biology, then the answer is no. For qualifying in NEET, you should score 50% of the Top score. For example, if you belong to General Category and the top score in NEET is 600, to qualify in NEET, you should score 300 as an accumulated score from all the 3 sections. It is 40% for SC,ST,OBC. Now during tie breaks in the due process, Higher marks in Biology will be given preference first followed by higher marks in Chemistry. So it is important to score good in these 2 subjects.
