To prepare for the exam whole day study is not possible as your mind also require little breaks to memorise the things you study. Here are some preparation tips for NEET you can follow:
Know the syllabus of the examination well :- NEET syllabus is as vast as an ocean, and you need to know the exact location to fish the best output. Cut down on extra information and focus on important topics.
Come up with an effective study plan :- Time is priceless. We all know this, yet many aspirants fail to make the proper use of time. Goal setting can be used as a strategy to help aspirants bring positive changes into their lives.
Work on weaker areas :- It is possible that you are very strong in one subject and weak in the other. Do not get discouraged by the same. Try and work hard more on the weaker areas to strengthen them.
Practice mock test papers :- One of the greatest challenges of the NEET examination is the time limitation. Students have to finish 180 questions in 180 minutes (3 hours).
Regular Study Breaks :- We are humans and not machines. So, we require timely rest as, after all, even machines need some rest to get back to working efficiently. Hence, it is essential to realize that one can’t maintain an optimum level of concentration without taking an optimum break to recover.
Use New Technologies :- There are many people who study by highlighting in the textbooks and making notes with a pen on a scrap of paper. These methods still find their place and importance, but there are countless options for personalising study than ever before.
Positivity is imperative :- Your attitude decides the effectiveness of the learning process. If you possess a negative approach and keep saying that you can’t do it, then this won’t commit to the idea of learning.

Good Luck!
