Chemistry Preparation

JEE Advanced Preparation - Chemistry

Chemistry is a combination of chemical equations and reactions, concepts and theory which requires much practise. For scoring good marks in chemistry one should practise as much as possible.

  • Understand the Concepts: One must understand the basic concepts, as once the concepts are clear nothing seems hard.
  • Make Notes: Make the notes of important points from each topic you study.
  • Practice with previous year papers and mock tests: The chemical equations and problems must be practised on a regular basis for better understanding. Practicing is the most crucial component of ones preparation. Practice and analyze your performance constantly.
  • Solve Questions Everyday: Give mock tests to attain perfection in the subject, which will improve the marks.
  • Use limited and accurate resources: Don’t try to cover the syllabus from multiple sources, you must practice from NCERT well. Along with that, you can read different concepts from a few acknowledged sources

Chemistry Experts Tips

JEE Advanced Chemistry- Paper Attempting Tips as per Experts

Chemistry is often considered the most scoring section by test takers and experts in JEE Advance exam. Being the most scoring section, chemistry often turns out to be a major rank uplifter for one’s overall performance in JEE Advanced. Candidates must attempt the exam carefully and calmly.

  • Try to attempt the chemistry section first: Chemistry questions include a major portion of fact based questions. Therefore solving them first will save much time. The time left can be then used for the physics and maths sections which are more time consuming.
  • Identify answers through approximations: Candidates must remember that the time is limited so try to solve accordingly. If one gets an approximate answer try to pick the option closest to it and mark the same.
  • Manage your time wisely: Time management in the chemistry paper is of utmost importance, candidates can save time in direct questions and invest the time left in other questions.
