Hi

I am extremely sorry to tell you dear but as you have filled ews as your category in NEET examination you will be treated as ews candidate only ,now nothing can be done and you can not change it to obc,

Neet 2020 qualifying cutoff is given below for different categories:-

Category    cutoff percentile       cut off marks

General/ews          50                            720  -  147

UR - PWD        45                        146  -   129

Obc/Sc/st         40                      146  -  113

So , a student from ews category requires at least 147 marks to qualify Neet 2020 examination , so with 117 marks you have failed in NEET examination

you may try again for Neet next year  and if you prepare again, you can use our Neet knockout program for which link is below
