Physics NEET MCQs for Better Score

Students appearing for NEET are primarily aspiring to become medical professionals. Thus, their primary focus is on biology, and as a result, they tend to struggle in solving other subjects like physics and chemistry. However, students should keep in mind that if they want to score high and secure a better rank, chemistry and physics MCQs should not be neglected.

FAQs on Physics NEET MCQs 2025

1. What is the qualification to sit for neet exams?

In order to sit for the NEET Exams, it is mandatory that a candidate must have passed 12th with the core subjects physics, chemistry, biology, and English from a recognized board of education. The aggregate marks for PCB should be 50 per cent for UR, 40 per cent for OBC, Sc and ST, and 45 per cent for PWD.


For more insight into the topic, the candidates can refer to the website of Vedantu where all the information is updated so that the candidate is never left behind on anything. 

2. What is the benefit of the NEET exam?

NEET is a common entrance exam for candidates who wish to pursue the medical field. 


This determines the qualification of the aspirant to get admitted for MBBS and other such undergraduate degrees. These exams prevent any private university or college from conducting their own exams. Students who qualify for NEET are given equal opportunities to secure a seat in any medical college in their desired state. All the more, students with high marks in this exam, also get the opportunity to get admission to the most prestigious medical colleges and institutes of the country. 

3. What Are Some Of The Popular NEET MCQ Books?

Some of the best NEET MCQ books for final preparation are Aakash modules, MTG question bank for Physics, Objective Biology by Dinesh, and NCERT Biology of Class XI and XII. Moreover, students can use the previous year’s question papers for reference.

4. How Many Times Is The NEET Exam Conducted Within A Year?

The NEET exam is conducted once a year. Even though there have been requests from students for this exam to be conducted half-yearly, NTA has not made any decision on this matter.

5. How To Become A Doctor In India Without Clearing NEET?

If you complete your medical graduation abroad and then clear the MCI exam, you can practise as a certified medical professional in this country. Otherwise, you have to clear the NEET exam.
