JEE Main Physics Syllabus 2019

JEE Main Physics Syllabus

Candidates who are preparing for JEE 2019 need to go through the Physics syllabus to know about the topics and subtopics included in the exam and accordingly they can plan their preparation for JEE 2019 Physics. The JEE exam has been fragmented into two phases which are JEE Main and JEE Advance. NTA (National Testing Agency) has decided to conduct JEE Main two times in a year. The first JEE Main is already over which was held in January in two shifts for Paper I and Paper II. The mode of exam was online for Paper I and Paper II, except the drawing test to check sketching skills of the candidate is in offline (pen-paper based) mode. The students who qualify JEE Main with good score can take admission in various engineering institutes like NITs, IIITs and CFTIs which comes after IITs in ranking.

The candidates who qualify JEE Main 2019 with high score are eligible to appear for JEE Advance 2019. The candidates who get high score in JEE Advance can get admission into one of the 23 IITs for various engineering courses. Physics is one of the important subject for JEE, the questions in JEE from physics are based both on theoretical concepts and application as well so it is important to understand the concept first, and practice questions based on each topic from both categories belonging to theoretical and numerical. For preparation of JEE Physics, the candidates can go through the detailed syllabus given below so that candidates do not miss out the important topics.
