Hi

Yes ,you can qualifying neet to exam even if you attempt only biology and don't attempt Physics and Chemistry i. e get zero marks in physics and chemistry.

This is because

There is no sectional cutoff in NEET examination i. e there is no separate cut off for each of physics chemistry and Biology in NEET examination , there is only overall cutoff .

For example,

In neet 2020, a general category required at least 147 marks to qualify Neet examination so let's say if a candidate had attempted only biology then also he was qualified for neet provided he had at least 147 marks in biology.

To help you further,

When we go through past year qualifying cut off trends then last 3 years qualifying cut off data is given below for reference :-

.                 .  Year wise cut off marks

Category     2020             2019          2018

General   720-147        701-134      691-119

UR-PH     146-129         133-120      118-107

Obc/sc/st  146-113     133-107       118 - 96

So , to be on the safer side you should try to get at least 15 to 20 marks more  in comparison of Neet 2020 cut off as per your category i. e if you belong to general category then try to get atleast around 165 marks in order to qualify Neet 2021.

Now , limited time is left for your neet 2021 examination, so focus on preparation, go through the chapters , practise questions and then revise them, go through mock test papers once you are done with complete syllabus.

Thank you
