Hello Aspirant, NEET is one of the toughest exam one has to crack, yes, you can crack it even now as there are 5 months still for the exam, one cannot give advice on how much time to read per day but I suggest you to focus completely on the weightage criteria for NEET according to chapters from subjects, you must solve mock tests to get better understanding on what kind of questions are being asked.

Hope this helps.

Thank you.
