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!!!
