Hello,

Yes, you as a Bachelor of Science graduate in home science can appear for the GATE 2026 exam, as the eligibility criteria include graduates from "Science" and other fields, as well as those in the 3rd year or higher of an undergraduate program.

I hope it will clear your query!!

Hey! The GATE exam (Graduate Aptitude Test in Engineering) is very important for long-term career growth. It opens opportunities for postgraduate studies (M.Tech, MS, PhD) in top institutes like IITs and NITs and is also used by many public sector companies (PSUs) for recruitment, often with higher salary packages. In the long run, qualifying GATE can enhance your technical knowledge, career prospects, and credibility in the engineering field.

If your GATE application shows failed status even after a successful payment, don’t worry, this usually happens due to server or transaction update delays. First, wait for 24–48 hours as sometimes the status gets updated automatically. If it still shows failed, you should raise a query through the GATE application portal by providing your enrollment ID and payment receipt or transaction details. You can also contact the GATE zonal office via email or helpline with proof of payment. Keeping a screenshot of the payment success message will also help in resolving the issue quickly.

BEST REGARDS

Hey! The qualifying cutoff for GATE CSE in 2025 was around 29.2 marks for General, 26.2 for OBC/EWS, and 19.4 for SC/ST/PwD. For GATE 2026, the official cutoff is not declared yet, but if we look at the past trends, it usually stays around 30–32 marks for General category. So, if you are preparing, it’s better to target a score well above this range to be on the safer side.
