I think neet should be your 1 priorty because you wants to become a doctor so there is no such importance of percentage ,you will get in your boards and syllabus is also same. So you should focus on your neet . if u didn’t understand then you will regret when you have to drop a year for neet.
There can be other situation also.
If u focus on neet and in boards suppose you get average percentage and you also fail to clear neet then you will think that you have lose both things but it is not like that , if you deeply think about that then there is a feeling of satisfaction that you have given your 100% .
So there will be no regret afterwards.
And if u suceed in clearing the neet then it will be the happiest moment of ur life And I will also be happy for u.
