Hello Aspirant,

See there is no any fixed amount of time for completing the NEET UG syllabus because t depends upon the capability of student, how much he/she can focus and concentrate and roughly speaking for an average student, if he/she devotes at least-4-5 hours a day then to read the entire syllabus of NEET UG it will take around 1.5 years to complete the syllabus as it consists of class 11th and 12th syllabus both.

For your reference I am mentioning down the syllabus of NEET UG :-
