If your syllabus has been thoroughly completed and you’ve practiced enough questions from every chapter that makes you confident enough to say that no concept is untouched then of course! You will definitely crack it if you are positive about it and do well in mocks.
I am in exactly the same position as yours and I believe thousands of other aspirants also. But what keeps us still in the same category of “can i crack neet in xyz months left for exam?” is totally we ourselves not putting in actual work till now.
So get stubborn and crazy for putting in real efforts in the last few days. Boycott everything that makes you wanna leave your study table, books and notes.
If your friends are calling you to hangout. Say NO
If you are tempted towards watching YouTube videos or strategy videos. Say NO (you already know your strategies yourself, practice and revision, that’s it)
If you feel uninterested within an hour of studying, this is where your will and passion is tested…you have to hang on until you’re tired and ready to go take a nap or rest.
