If you have studied physics ......then do imp topics which cover more weightage in neet paper.... ...if you haven't studied physicis ......then do part 2 of class 11 th and 12 th sincerely after. doing this you can easily do 20-23 question right in neet and from first part which ever chapter you can do do that also......if you have given your. 12 th boards this year then you must have studied whole physicis and then just revise 12 th physics and do part 2 of 11 th class physics sincerely do them then you will be able to solve around 30-34 question in exam.....along with these you have to solve last 5-7 years of neet Paper also ...best of luck....
