JEE Main Exams:
A Comprehensive Insight
The Joint Entrance Examination (JEE) Main is a national-level entrance exam in India conducted by the National Testing Agency (NTA) for admission into undergraduate engineering programs at NITs, IIITs, GFTIs, and other engineering colleges. It is also the qualifying exam for JEE Advanced, which is required for admission into IITs.
Academic Benchmark & Foundation for Higher Studies
CBSE board exams (Class 10 & 12) serve as a standardized assessment to evaluate students’ understanding of subjects at a national level. They help maintain uniformity in education across the country.
The results determine subject selection for higher secondary education (Science, Commerce, Arts) and play a crucial role in college admissions, with many universities and entrance exams considering them for eligibility.
CBSE curriculum aligns with major entrance exams like JEE, NEET, and CUET, making board exams a stepping stone for these competitive tests. Good conceptual understanding in board exams helps in cracking national and state-level exams. CBSE board results hold value nationally and internationally, making it easier for students to apply to foreign universities.

| 2020 | Introduction of Numerical-Type Questions (No negative marking). |
| 2021 | Increased to four attempts per year due to COVID-19. |
| 2022 | Back to two attempts per year (January & April). |
| 2023 | 75% eligibility rule reinstated: Students must score at least 75% in Class 12 for NITs, IIITs. |
| 2024 | More weightage to application-based & logical reasoning questions. |
📌 Expected Future Changes: AI-based analysis of student performance and personalized feedback systems.
4. JEE Main Cutoffs & Percentile System
JEE Main uses Percentile Ranking, not raw marks.
| Year | General Cutoff (JEE Advanced Qualifier) |
|---|---|
| 2020 | 90.37 percentile |
| 2021 | 87.89 percentile |
| 2022 | 88.41 percentile |
| 2023 | 90.77 percentile |
📌 Top 2,50,000 rankers qualify for JEE Advanced (IIT Entrance).
5. Preparation Tips for JEE Main
✔ NCERT is the Key – Strong understanding of NCERT concepts is crucial.
✔ Practice Previous Year Papers – Helps understand patterns & difficulty levels.
✔ Time Management – Allocate time to high-weightage topics.
✔ Mock Tests & Analysis – Attempting JEE mock tests in real exam conditions is vital.
✔ Smart Revision – Use flashcards, summary notes, and short formula sheets.
📌 High-weightage Topics
