# Physics NEET MCQs

## 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 the 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.

With the NEET 2020 around the corner, as a student you must be gearing up for your final revisions. Therefore, having a set of selected physics objective questions and its answer key at hand can prove to be immensely helpful. In this article, you can find such selected physics questions as per chapters.
