Hello,

Congratulations on achieving a 90.3 percentile in JEE Main 2025! As an SC category female candidate , you have a favorable position in the admission process for NITs. Let's assess your chances for Computer Science and Engineering (CSE) at NIT Goa and explore other potential NITs.

Understanding Your Rank:

• Percentile to Rank Conversion: With a 90.3 percentile , your approximate Common Rank List (CRL) rank would be around 97,000 out of 1,000,000 candidates. For the SC category , this translates to an approximate category rank of 6,000 to 7,000 .

NIT Goa CSE Admission Chances:

• Previous Year Cutoffs: In 2024, the SC category closing rank for CSE at NIT Goa was 2,445 .

• Analysis: Given your estimated SC category rank of around 6,000 to 7,000 , securing a seat in CSE at NIT Goa may be challenging, as the previous year's cutoff was significantly lower.

Alternative NITs to Consider:

Based on previous years' data, here are some NITs where the SC category closing ranks for CSE were higher, indicating a better chance of admission:

• NIT Agartala: Closing rank around 3,682 .

• NIT Puducherry: Closing rank around 3,160 .

• NIT Sikkim: Closing rank around 3,803 . https://www.careers360.com/

• NIT Arunachal Pradesh: Closing rank around 4,295 .

Recommendations:

1. Participate in JoSAA Counseling: Engage actively in the JoSAA counseling process, listing multiple NITs and branches to maximize your admission chances. https://www.careers360.com/

2. Consider Related Branches: If CSE is highly competitive, explore related branches like Information Technology (IT) or Electronics and Communication Engineering (ECE) , which may have slightly higher cutoffs.

3. Stay Updated: Regularly check the official JoSAA website and individual NIT portals for the most current cutoff information and counseling updates.

Please note that cutoff ranks can vary each year based on factors like the number of applicants, seat availability, and exam difficulty. Therefore, while historical data provides a reference, it's essential to stay informed about the current year's trends.

Best wishes for your counseling process and future academic endeavors!

Hello,

Regarding your query there is no single "best" between JEE and NEET the choice depends on individuals understanding, interests, and career aspirations. While JEE s for aspiring engineers NEET is for aspiring doctors.

• For: Students passionate about mathematics, physics, and chemistry, who enjoy problem-solving and logical reasoning, and aspire to careers in engineering, architecture, or related fields.

  
  
• Career Options: Computer Science, Mechanical Engineering, Electrical Engineering, Civil Engineering, Chemical Engineering, and more.

  
  
• Exam Focus: Emphasizes mathematics, physics, and chemistry, with a focus on problem-solving and analytical skills.

  
  

• For: Students passionate about biology, chemistry, and physics, who aspire to careers in medicine, dentistry, or related healthcare fields.

  
  
• Career Options: MBBS (Bachelor of Medicine, Bachelor of Surgery), BDS (Bachelor of Dental Surgery), and other medical specializations.

  
  
• Exam Focus: Emphasizes biology, chemistry, and physics, with a focus on understanding and applying scientific principles.

  
  

Hello,

Regarding your query please elaborate your question so we can further address your queries.

No, with an NTA score of 52.24 in the General category, you are unlikely to qualify for JEE Advanced as this score is significantly below the required cutoff for the general category. To be eligible for JEE Advanced, you typically need an NTA score well above 90 percentile.

Key points to consider:

Low percentile:

A 52.24 NTA score translates to a very low percentile, which means you rank much lower compared to other general category candidates.

JEE Advanced cutoff:

The minimum required percentile to qualify for JEE Advanced in the general category is usually much higher than 52.24.

What you can do:

Focus on improving your score:

If you really want to attempt JEE Advanced, consider preparing for the next JEE Mains attempt with a goal of achieving a much higher NTA score.

Explore other options:

While you may not qualify for top IITs with this score, you can still explore admission to other good engineering colleges that accept JEE Mains scores based on your percentile

Hello,

Securing admission to Veer Surendra Sai University of Technology (VSSUT), Burla, or Odisha University of Technology and Research (OUTR), Bhubaneswar, with a JEE Main rank of 4.5 lakh under the ex-servicemen quota is challenging, especially for sought-after branches like Computer Science and Engineering (CSE), Information Technology (IT), and Electronics and Communication Engineering (ECE).

Understanding the Ex-Servicemen Quota: The ex-servicemen quota is typically a horizontal reservation, meaning it cuts across various categories such as General, OBC, SC, and ST. Since you belong to the OBC category, your admission would be considered within the OBC category with the ex-servicemen reservation applied.

VSSUT, Burla: Specific cutoff ranks for the ex-servicemen quota are not readily available. However, general trends indicate that highly sought-after branches like CSE have much lower cutoff ranks. For instance, the expected cutoff for CSE is between 47,176 and 47,181 for general category students. Given your rank, securing admission in top branches at VSSUT may be difficult. https://www.careers360.com/

OUTR (formerly CET), Bhubaneswar: Similarly, detailed cutoff information for the ex-servicemen quota at OUTR is limited. Previous data suggests that the closing rank for B.Tech in Civil Engineering was around 244,549 for general category students. This indicates that less competitive branches may have higher cutoff ranks, but a rank of 4.5 lakh still poses a significant challenge.

Recommendations:

1. Explore State Counseling: Participate in the Odisha Joint Entrance Examination (OJEE) counseling process, as state-level counseling may offer more opportunities, especially under specific quotas.

2. Consider Alternative Institutions: Research other engineering colleges in Odisha and neighboring states that may have higher cutoff ranks, increasing your chances of admission.

3. Look into Management Quotas: Some private institutions offer management quota seats, which might have different eligibility criteria.

4. Prepare for Spot Rounds: Stay informed about spot or mop-up round counseling sessions, where unfilled seats are offered, sometimes with relaxed cutoff ranks.

5. Evaluate Other Engineering Disciplines: Be open to enrolling in engineering branches that are less competitive, as they may have higher cutoff ranks.

Hello,

Yes, you will be eligible for JoSAA counseling in 2026 if you meet the following conditions:

JoSAA Eligibility Rules

• JEE Main Qualification – You must qualify JEE Main 2026 with a valid rank.

• 12th Board Exam Qualification – Your improvement exam in 2026 will be considered, and your latest marks will be valid for eligibility.

• Minimum Percentage Requirement –

For NITs, IIITs, and GFTIs , you need at least 75% marks (65% for SC/ST) in the 12th board exam OR be in the top 20 percentile of your board.

For IITs , you need to qualify JEE Advanced and meet the 75% (or top 20 percentile) rule.

Important Notes:

• JoSAA considers the latest board exam result for eligibility.

• Since you will be appearing for an improvement exam in 2026 , your 2026 marks will be considered for eligibility, not your 2025 results.

• You must ensure that your improvement exam covers all subjects , as JoSAA does not accept partial improvements (only in some subjects).

Hello,

Unfortunately, you are not eligible to appear for JEE Advanced 2025 even if you qualify JEE Mains.

Why?

The eligibility criteria for JEE Advanced state that a candidate can attempt the exam only twice in consecutive years after passing Class 12.

• Since you passed Class 12 in 2023 , your two chances to write JEE Advanced were in 2023 and 2024 (provided you qualified JEE Mains).

• You skipped JEE Advanced in both years, which means you are no longer eligible for JEE Advanced 2025 .

What Can You Do?

1. Focus on JEE Mains: You can still get into NITs, IIITs, and GFTIs if you score well in JEE Mains.

2. Consider Private or State Engineering Colleges: Many top private colleges accept JEE Main scores or conduct their own entrance exams (e.g., BITS Pilani, VIT, SRM, Manipal, etc.).

3. Explore Other Career Options: If you are open to different career paths, you can consider other entrance exams or alternative fields.
