I tried to edit the data of GEN -> OBC-NCL, but it says "Something went wrong please try again". Is this error on my side or everyone. #GATE #GATECorrectionWindow

This is likely a temporary portal or validation issue, not something you did wrong. When candidates try to change category from GEN to OBC-NCL during the GATE correction window, the system checks required fields and sometimes a supporting certificate or fee is needed. If any required data or document is missing, or the server is busy, the portal can show Something went wrong, please try again. Explain to them that first they should log into the GATE portal, open the Correction tab and confirm which fields are editable and whether a payment or document upload is required for category change. Tell them to clear browser cache or try a different browser/device and retry. If the error persists, advise contacting GATE support or the zonal office with a screenshot and timing of the error so officials can check server logs.

The GATE 2026 Agricultural Engineering (AG) paper will have a total of 100 marks. Out of this, 15 marks are for General Aptitude and 85 marks are for core Agricultural Engineering subjects.

The marks are generally distributed among major topics like Engineering Mathematics (12–13 marks), Farm Machinery (10–11), Farm Power (14–15), Soil & Water Conservation (12–13), Irrigation & Drainage (10–12), Agricultural Process Engineering (10–12), and Dairy & Food Engineering (9–10 marks).

The official qualifying marks for GATE 2026 are not yet released. However, based on previous years, the cutoff for the Agricultural Engineering paper is expected to be around 25 marks for General, 22.5 for OBC/EWS, and 16.6 for SC/ST/PwD candidates.

Hope it helps !
