Hey there ,

Hope you are doing well . See , you have given NEET and are now participating in the Counselling,that means you were eligible for the exam i.e. your aggregate was atleast 50% in Physics, Chemistry, Biology and English in 12th standard from a recognised board. So ,if you filled a bit incorrectly in part 1 and you have also mentioned that there isn't a very big difference in the percentages so I don't think there'll be any issue as such .

Hope this helped .
