It’s difficult to say, bcz all the toppers who come under top-50 in neet every year have almost same potential to be topper but it depends on his/her luck on that day.
Even after mastering ur concept very well no one will take responsibility that you would get full marks in any examination.
So it’s good to be the target of full marks and devote ur self in study accordingly, but not be so egoistic that leads to make you depressed even after getting decent marks.
One more secret is that you have to do is smart work instead of only hardwork, make every concept crystal clear, after that do lot of questions everyday, bcz only after knowing concept you would not be so perfect in exam, so do lots of practice bcz practice makes perfect and after gaining perfection, In examination hall you will feels like every question you have done previously during practice, so it will increase your accuracy which may help you to get full marks.
