  • 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
