Now i am in class 12th and i starting preparation for neet in this month can you give me a best way for i clear neet in this year.

Preparation for NEET involves a lot of aspects:
- BOOKS: Please follow the link https://www.careers360.com/question-to-score-top-ranks-in-neet-which-book-should-be-preffered?icn=question-title-details&ici=topic-detail-page
- PAPERS: When you practice these papers, solve them in a mock exam format and analyse your papers after that, outlining strengths and weaknesses. These questions are seldom repeated, their main purpose is to develop time management skills. Here are some links: https://www.entrancecorner.com/medical/articles/neet-2018-sample-papers/ http://www.careerpoint.ac.in/free-sample-paper/neet-sample-papers-download.aspx https://medicine.careers360.com/articles/neet-sample-paper
- STUDY MANAGEMENT:
1) Skills: Everybody shows a diversity of study skills and tactics. To know how you learn best, check out this site, http://vark-learn.com/ It contains a questionnaire that will tell you your learning preference and various strategies to strengthen it further.
2) Habits: You need to figure out which duration of the day you attain your peak concentration levels and do the most difficult topics during that time. Study the other topics during other timings. Also, figure out which place is most ideal for you, clear of things you find distracting. 3) Planning: The old saying, "If you are failing to plan, then you're planning to fail" applies here as well. It saves a lot of time as you have an agenda of what you want to accomplish. Don't be disheartened if you are not able to complete one of the goals, no plan can be 100% perfect. I recommend, not to make rigid plans, keep it flexible
- MANAGING YOURSELF: Preparing for this exam is not an easy feat but it is a learning experience. You should also enjoy and keep yourself happy, otherwise a bitter attitude will take a toll on you later
