JEE Main Preparation Tips for Class XI and XII Students

This section highlights JEE Main preparation tips for class XI and XII students.

Boards are Important!

Understanding Weaknesses

• Many JEE Main 2021 aspirants take 11th class lightly to focus on 12th exams which is a wrong approach
• Class XI subjects consist of topics that create a base for the topics of Class XII
• To make concepts of 12th clear, one must understand the basics of the same in 11th class itself.

Time Flies!

• Time management is important
• Manage time in such a way that you get enough time for studying, doing household chores, leisure and other activities
• Initially start by calculating the time consumed in day-to-day activities using a stopwatch
• Then, prepare a time limit for every activity
• Give a major portion of time for studies

Create Short Notes:

• Students must create a habit of maintaining short notes of important topics of JEE Main 2021
• This helps in revision a few days before the examination
• Short notes are handy when time is less
• Also, short notes are useful when one just needs to revise formulas, equations and short cut methods.

Do Not Procrastinate

• It is not possible for JEE Main aspirants to decide how long will it take to cover entire JEE Main syllabus or JEE Advanced syllabus
• Some benefits from the rigorous study while some scores well with less effective study
• Stay focused and do hard work to a limit which is required
