Frequently Asked Questions

Which is the hardest paper in JEE Mains?

JEE Main is conducted in various shifts, and the difficulty level varies shift-wise. January 2023 (Shift 2) and April 2019 (Shift 2) papers are among the toughest JEE Main Exams based on past trends. Maths is generally the most difficult, with Physics being more difficult than Chemistry in general.

Hardest JEE Main Papers (Past Years)

Year & Session Difficulty Level Toughest Subject Key Challenges
Jan 2023 (Shift 2) Very Hard Mathematics Time-consuming and complex calculations
April 2019 (Shift 2) Hard Mathematics Coordinate geometry and complex integration
July 2021 (Shift 1) Hard Physics Conceptual and challenging numerical problems
Sept 2020 (Shift 2) Moderate-Hard Mathematics Calculations that take a long time

Which is the toughest subject in the JEE Mains?

Out of the 3 JEE Main subjects, Mathematics is usually the most challenging because of its long calculations, complicated problem-solving, and higher-level conceptual application.

Subject-Wise Difficulty level of JEE Main

Subject Difficulty Level Key Challenges
Mathematics Most Difficult
  • Lengthy calculations
  • tricky problem-solving
Physics Moderate to Hard
  • Concept-heavy
  • numerical-based
Chemistry Easiest to Moderate
  • Memory-based
  • requires strong theory knowledge

Are polymers important for JEE mains?

Yes, Polymers hold importance for JEE Main with 2-3% weightage in Chemistry. Questions are predominantly theory-based and involve types, polymerization, and familiar examples such as Nylon, Teflon, and Bakelite.

It is an easy scoring and simple topic, and a simple manner of scoring marks.

What are the essential amino acids for JEE?

For JEE Main, essential amino acids are those that the body is unable to produce on its own and must be received through diet.

The following are the main important amino acids:

  • Methionine
  • Valine
  • Leucine
  • Isoleucine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Lysine
  • Histidine (essential for children)
