In a battle against thousands of competitors and time, applicants must thoroughly understand the NEET 2022 Physics Syllabus. The NEET 2022 Physics Syllabus includes a wide range of conceptual and theoretical concepts, each with numerical problems. The National Testing Agency (NTA) has increased the total number of questions in the medical entrance examination to 50, wherein students need to attempt 45 questions from the Physics section, making 180 marks from the total NEET 2022 marks.
According to the revised NEET 2022 Exam Pattern, the NEET 2022 Physics paper will have 50 questions, split into two sections, Section A and section B. Wherein section A comprises 35 questions and section B with 15 questions, respectively. In section B, students will have the option to answer only 10 questions.
