First of all thanks for the question.
You can surely crack neat in the time duration of 1 year if your study plan is very proper and you are very sincere regarding your goals.
This journey will require a lot of dedication, optimism,self discipline and most important a lot of hard work.
Now the question may arise?How to do it??? As every problem have a solution. It has also.
So I have some tips for it 👇
1.Complete your syllabus as soon as possible.
2. Be selective instead of collective.
Means you should mainly focus on NCERT text Books instead of other reference books. Because all the questions in NEET are asked directly from NCERT.
3.Solve all the PYQ (atleast of 10 years )
4.if you can ,then solve 2 years PYQ of JEE also.
5.Attempt all the mock test and analyse them properly.
