The structure of the NEET question paper has changed in the past two years. According to the latest NEET exam pattern, each subject consists of two sections. Section A will consist of 35 questions and Section B will have 15 questions. Out of these 15 Questions, candidates can choose to attempt any 10 Questions. So, the total number of questions remained the same. The duration of the exam has increased by 20 minutes and the total duration is 200 minutes or 3 hours and 20 minutes.

NEET preparation is a time-consuming affair and it should be done with a systematic approach. The first and foremost step is to know the syllabus for NEET UG properly. The best part about the NEET syllabus 2025 PDF download topic-wise is from the Class 11 and Class 12 syllabi and students are already familiar with the key concepts. However, NTA has released the syllabus in English only and candidates opting for regional languages or Hindi would have to look for the syllabus in Hindi or the respective regional languages. Such candidates can seek the help of their teachers and mentors to provide them with the NEET syllabus 2025 PDF download in Hindi or other languages. To prepare for the NEET new syllabus, candidates should follow the steps given below:

• Be thorough with the concepts: Students should know the concepts of the important topics from the NEET subjects. They should ensure that there is no gap in their understanding. In case of any doubts or queries, they should approach their mentors or teachers. Suggesting on the strategy to complete the NEET syllabus, Saurabh Kumar, Chief Academic Officer, Vidyamandir Classes says, "Make sure that the complete syllabus is covered in the first three months, which includes portions from both Class 11 and 12. Since aspirants might be fresh with the Class 12 portion of the NEET syllabus, the initial time should focus on covering the Class 11 portion to rewind things. And most importantly do not opt to study new topics/ concepts at the last moment."
• Strategy for subject-wise NEET syllabus completion: Candidates must focus on completing the NEET syllabus for each subject. While doing so, candidates may note that even though the weightage of the NEET Biology syllabus is higher, it would not be tougher than Physics. On the other hand, the number of topics in Physics or Chemistry may be lower, but the difficulty level, vis-a-vis the time taken to complete the syllabus would be higher. Talking about this, Saurabh Kumar mentions, "Though the Biology portion (Zoology and Botany) may be a bit easier in comparison to Physics, which has a higher number of theoretical and numerical questions. Biology students need to focus and practice more in the Physics section." 
• Refer to the best books: While there is no dearth of books to prepare for the syllabus of NEET 2025, students should be careful in selecting those. The factors that need to be kept in mind include the coverage of the NEET syllabus, language quality and reading experience, practice questions and solutions and edition. NCERT is the best and the most popular book to refer to for NEET 2025 preparation. Hence, they should first complete the NCERT books and after that, they should move on to other NEET preparation books or study materials.

• Get enough practice: As they say, practice makes a man perfect. In order to test whether the preparation of a particular section of the NEET 2025 syllabus is complete or not, candidates should take NEET mock tests or solve practice papers regularly. After that, they should analyse their performance to know where they can improve further. 
• Analyse strengths and weaknesses: Analysing one's strengths and weaknesses is very important as it helps the student understand where he/she is standing in comparison with other candidates. With less than a month to go for the exam, it is high time that they focus on their strengths and don't stress over their weak areas. However, before leaving out a topic completely, students should check its weightage and then decide. 
• Revision: Regular revision is key to NEET preparation. After completing each chapter from the NEET 2025 syllabus, prepare notes on the key points along with charts, tables or diagrams to make it easily comprehensible. Browse through the revision notes regularly to not lose touch on those topics even after completing the basic preparation.
