Hello aspirant,

If you missed the correction window for GATE 2026, the portal will not allow changes right now. Usually, IIT opens a correction period only once. Since you need to change your surname, the best option is to contact the GATE organizing institute through their official support email or helpline and explain your issue with valid proof like your Aadhaar or school documents. They sometimes allow corrections in genuine cases, but it depends on their approval. Make sure to keep all documents ready when you contact them.

THANK YOU

Hi Aanchal,

Balancing Engineering semester exams with competitive exam preparation can feel confusing but with right and realistic routine makes it very achievable.

Start by dividing your day into two parts: use college hours and afternoons for semester prep and keep early mornings or late evenings for GATE prep.

Make weekly targets instead of daily pressure, revise class notes on the same day.

Use weekends for mock tests, previous year papers and deeper revision.

Try to limit social media, study in 40 to 50 mins focused blocks and take short breaks.

Most importantly stay consistent and give yourself patience.

With consistent timetable and steady effort you can manage both in smooth. All the best Aanchal!

If you are interested in Development Studies and planning to appear for GATE XH C6 (Sociology), then you are already moving in the right direction. Having a backlog does not disqualify you from pursuing higher studies, as long as you clear it before the admission process begins. Since you mentioned that you can clear the backlog before February 2026, it should not affect your eligibility for PG admissions. Most universities require a completed bachelor’s degree with no active backlog at the time of admission.

Your CGPA of 6.9 is acceptable for many institutes, although some top institutes may have higher cutoffs. Your interest in sociology and Development Studies will be helpful because the GATE XH paper tests conceptual understanding. If you prepare consistently and score well in GATE, you can apply to reputed institutes offering Development Studies such as IITs, TISS, JNU, Azim Premji University, and others.

Focus on clearing your remaining backlog and continue your GATE preparation strongly. If you balance both, you can build a good academic profile for admission into Development Studies. All the best.


Hello,

You can change your category in the GATE application by logging into the GOAPS portal during the correction window and using the "Edit GATE Application Form" option to make the change. You will likely need to pay an additional fee for the change and may need to provide a valid category certificate.

I hope it will clear your query!!

Hello,

Other than the GATE exam, admission to MTech programs in Data Science/AI for 2026 includes university-specific entrance tests like VITMEE, BITS HD Entrance Test, and SRMJEEE PG, as well as state-level common entrance tests such as Karnataka PGCET and TS PGECET.

I hope it will clear your query!!
