## Why covering complete JEE Main physics syllabus is beneficial

The JEE mains exams require the candidate to have the utmost concentration and focus towards it. Millions of students appear for the exam every year and finally very few get a chance to study in some of the best engineering colleges in the country. While preparing for the exam, knowing  or completing the JEE syllabus whether it is for JEE Main or JEE Advanced plays a crucial role.

Here we shall discuss why it is important to cover the JEE exam syllabus.

• To Plan Efficiently

The Physics  will have marks allotted to each and every chapter. By knowing the syllabus and the marks allocation which is released by the NTA team every year, students can plan expertly. Some chapters will contain more weightage of marks and some will barely contain 1-2 marks. By learning the syllabus, candidates will know how to allocate the time amongst important chapters and less important chapters.

• Syllabus Acts As The Blueprint For The Examination

The syllabus released by the National Testing Agency (NTA) contains all the topics and subtopics covered under every chapter. Knowing the syllabus will keep aways from confusion regarding what to study and what not to.

• Helps You to Score Good In Exam

The syllabus gives you a clear idea of the JEE exam and what to expect from it. By learning the Physics syllabus, students can plan and prepare themselves accordingly to score good marks in the exam.

• Saves Time

By following the syllabus, there will be very less possibility of wasting time trying to guess the topics that may or may not appear in the examination. The examination syllabus should be followed rigorously to save more time and score good marks in the exam.

• Gain Control Over Learning

Knowing  the syllabus should be your first and foremost step before starting your JEE exam preparation. Spend more time on the topics covered under each subject and learn everything that is mentioned in the syllabus to achieve control over learning.

• Gets You Familiar With The Exam Paper

Knowing the syllabus and exam pattern released by the NTA will give you an exact idea of how the question paper will be designed. It will help you to get familiar with the question paper where you keep yourself away from confusion and exam fear during the mains exam. This will also help you to somewhat forecast the pattern of questions that might occur in the exam.
