You should prepare a time-table according to your suitability and preference. So, that you are comfortable to follow it. You should study atleast 6-7 hours a day. Plan a subject for a week or for a day. Solve MCQs related to the important topics. So, that you can grasp the topics. You should solve complete mock test series daily to check your performace level and to know your strength and weakness.

For Preparation make sure you follow NCERT books, previous year papers to understand the exam pattern and level of questions.

All the Best!!

Kindly share what is your preparation status as of now, also share are you taking coaching or preparing by yourself. But generally below preparation tips should be followed -

Know the syllabus of the examination well: The very first thing that candidates should know is the complete syllabus of the NEET-UG exam. You can compare the syllabus with your Board exam syllabus. Make a schedule of study for the week: Until and unless you make a complete and thorough schedule of the way you want to study, you will not be able to complete the syllabus

Work on weaker areas: It might happen that you are very strong in one subject and weak in the other. Do not feel disheartened by the same. Try and work hard more on the weaker areas to strengthen them. Practice mock test papers: One of the greatest hurdles of the NEET-UG examination is the time limitation. Candidates have to finish 180 questions in 180 minutes (3 hours). It means they can give a maximum of 1 minute per question. Do not fall for guesswork: Many candidates have the tendency of applying guesswork to questions they don't know. However, it might prove risky in this case as there is negative marking for a wrong answer.

Hope this helps!!!

Here are some of the important tips:

Understand the Syllabus: It’s imperative to know the syllabus thoroughly for the test so that you don’t waste time on irrelevant material. The NEET exam covers NCERT syllabus.

Subject-Wise Plan: You must plan your strategy differently for different subjects viz. Physics, Chemistry & Biology.

Sample Papers: You must practice a lot of sample papers and mock tests as you have to solve 180 questions in 180 minutes i.e. one minute per question. Hence, time management is of utmost importance in NEET exams.

Be Careful About Negative Marking : You get four points for every correct answer. However, guesswork could cost you heavily. NEET has negative markings.

Evaluate Your Strengths & Weaknesses: you can turn your weaknesses into strengths for a good overall score by focussing on your improvement areas.
