Check: Good Score in JEE Main 2025- Check Expected Marks Vs Percentile in JEE Main
| Score Range | Percentile (Approx.) | Implications |
|---|---|---|
| 250–300 | 99.9+ | Exceptional score; guaranteed admission to top NITs/IIITs with preferred branches like CSE. |
| 200–249 | 98–99.8 | Very good score; eligible for core branches in mid- and top-tier NITs. |
| 150–199 | 90–97 | Good score; likely admission to lower-tier NITs and state-level colleges. |
| 100–149 | 70–89 | Decent score; qualifies for JEE Advanced but limited options in top NITs. |
| Below 100 | <70 | Below average; opportunities limited to private or state-level colleges. |
Is 150 a Bad Score in JEE Main?
A score of 150 out of 300 in JEE Main is not necessarily bad, but its depends on the desired college, branch, and category. With a 150 score, a candidate can still qualify for JEE Advanced and secure admission to certain NITs, state-level colleges, or private institutions. Below is a detailed analysis of what a 150 score represents in JEE Main.
- A score of 150 typically corresponds to a 90–92 percentile in JEE Main (depending on the paper's difficulty).
- This percentile places candidates in the top 10–12% of all aspirants, which is competitive considering the exam’s scale.
| Aspect | Analysis |
|---|---|
| JEE Advanced Eligibility | The qualifying cutoff percentile for the General category was 93.23. |
| NIT Admission | With a percentile of approximately 98, your Common Rank List (CRL) would be around 20,000. This rank may secure you branches like Civil Engineering or Metallurgical Engineering in mid-tier NITs. |
| State Colleges | A CRL of 20,000 enhances your chances of obtaining preferred branches in reputable state-level engineering colleges, depending on state-specific cutoffs. |
| Private Colleges | This score qualifies you for top private institutions such as SRM Institute of Science and Technology, Vellore Institute of Technology (VIT), and Manipal Institute of Technology, where the typical cutoff ranks are higher than your CRL. |
Opportunities Based on 150 Score
Admission to NITs with 150 marks is realistic for branches like:
- Civil Engineering
- Metallurgical Engineering
- Biotechnology
| Category | NIT Admission Likelihood (150 Marks) | Example Colleges |
|---|---|---|
| General | Possible in lower-tier NITs | NIT Arunachal Pradesh, NIT Meghalaya |
| OBC-NCL | Mid-tier NITs for less popular branches | NIT Silchar, NIT Srinagar |
| SC/ST | Good branches in mid-tier NITs | NIT Calicut, NIT Jaipur |
JEE Advanced Qualification
- In 2024, the General Category JEE Advanced cutoff was 93.23 percentile, which is achievable with 150 marks.
- Scoring 150 qualifies candidates to compete in the next stage for IIT admissions, which can open further opportunities.
