NEET Physics 2020

NEET Physics, in general, comprises of six major units from class 11th and class 12th physics syllabus, namely, Mechanics, Electrodynamics, Modern Physics, Optics, Thermodynamics, and SHM-Waves. There are a total of 45 questions (180 Marks) in NEET Physics section. Most of the medical aspirants find Physics as the toughest among the other two subjects mainly because it consists of a wide variety of numerical problems, theoretical and application-based concepts.

NEET Physics demands consistent practice and a clear understanding of all the concepts and related formulae. Hence, to score well in this section the first step is to understand and memorize all the important concepts and formulae included in the syllabus. That would help the students to answer complex numerical problems quite smoothly. Solving numerical in physics can turn out to be a nightmare for many aspirants, as a result, they generally avoid its practice and accordingly they prioritize their focus on other sections, as a result, they are unable to score well in NEET Physics section that ultimately results in the lowering of their final NEET score.

NEET Physics 2020

Most of the NEET aspirants have a common habit of memorizing everything. This approach might be helpful in subjects like Chemistry and Biology, however, It will never help in the preparation of NEET Physics. Students are advised to take topic-wise online test series to have a complete analysis of their understandings of each and every concept. Also, while preparing any concept, try to relate it to its practical applications.

NEET Physics 2019 Analysis

NEET 2019 Physics section was moderate in terms of difficulty and length. Several questions were formula based. However, for better scores, the students were required to have a strong conceptual base along with the practical application of concepts. Aspirants found most of the questions appearing from NCERT syllabus, around 60% of the NEET paper to be precise. The Physics section was particularly found to be easy comparatively. NEET 2019 was considered to be easier than the previous years. Most of the questions were asked from the Mechanics and Modern Physics section

Questions were found to be taken equally from class 11 and 12 where topics – Mechanics and Modern Physics dominated with around 50% of the section. Questions that appeared from topics such as Magnetic Effect of Current and Current Electricity were easy. Also, since the paper for NEET 2019 was easier, there were high chances for the NEET cut-off to have increased.

Kinematics:

Kinematics is one of the most interesting and crucial units of NEET Physics. The problems based on the evaluation of the maximum height, range, velocity and time of flight (2 D motion) are important from the examination point of view. Maintain proper notes of all the theorems, formulas, and derivations to assist your last-minute preparations. Strengthen your concepts on acceleration, displacement, average, and relative velocity to score well from this unit.

The students can follow NCERT books for NEET to strengthen their theoretical concepts. For numerical problems, the students can refer to solved problems in Physics by Schaum. Concepts of Physics by H C Verma (Vol 1 & Vol 2) is helpful for both theoretical and numerical physics.
