# NEET Physics 2021

NEET Physics syllabus from class 11 and 12 has 6 prime units – Modern Physics,Β  Mechanics, Thermodynamics, Electrodynamics,Β  SHM-Waves and Optics. 45 out of 180 questions asked in NEET are from the NEET Physics section. In comparison to Biology and Chemistry, students often have a tough time dealing with Physics primarily because of the typology of questions appearing in this section. It consists of computations of numericals, theoretical and application types of questions and more.

NEET Physics necessitates round-the-clock practice coupled with an in-depth comprehension of concepts and associated formulae. In order to score well in NEET Physics, firstly learn and understand all important topics, including formulae as specified in the syllabus. This would be the first step to crack challenging numericals effortlessly. Physics numericals are deemed no less than a nightmare by students because of which they tend to overlook it and do not practise enough. As a result, they focus on strengthening other sections of NEET. This has been perceived as the major reason why students fail to score as much in NEET Physics, affecting their finalΒ NEET score.

One of the most common practices amongst NEET aspirants that has been observed is the rote learning technique, where one memorizes. While the approach has gained momentum in Chemistry and Biology section, helping students, the same cannot be applied when it comes to NEET Physics section. To get a thorough insight into your learnings, it is suggested to take up test series provided topic-wise for every topic and hence, correlating with its application practically.

## NEET Physics 2019 Analysis

NEET 2019 Physics section was deemed average in terms of complexity and length. Several questions were formula based. To crack the section with good marks, a strong and solid hold on concepts with its prompt application was inevitable. Aspirants found most of the questions appearing from NCERT syllabus, precisely close to 60%. The Physics section in particular was found to be comparatively easier. NEET 2019 was considered to be easier than the previous years. Most of the questions were asked from the Mechanics and Modern Physics section

Equal distribution of questions from both classes 11 and 12 was also taken note of. The topics that dominated NEET Physics section were Modern Physics and Mechanics, almost 50% of the section. Easier questions appeared from units such as Current Electricity and Magnetic Effect of Current. Also, since the paper for NEET 2019 was easier, there were high chancesΒ for the NEET cut-off to have increased.

Given below is the NEET Physics 2019 Analysis chapter-wise:

 Name Of The Unit Number of Questions Weightage Marks Current Electricity 3 6.66% 12 Electrostatics and Capacitor 4 8.88% 16 Heat and Thermodynamics 3 6.66% 12 Magnetism, Magnetic Effect of Current and AC 5 11.11% 20 Mechanics 17 37.82% 68 Modern Physics 6 13.33 24 Properties of matter 3 6.66% 12 Ray and Way Optics 4 8.88% 16 Total 45 100 180
