Who can apply
You need a WBJEE 2026 rank and a 10+2 pass in regular class mode with Mathematics, Physics and Chemistry. The three subjects together need at least 60% marks (55% for SC, ST, OBC, PWD and EWS), you must pass each subject on its own, and English needs at least 30%. JEE Main is not applicable.
Prepare your uploads before you open the form
- Resize the photo to 50KB or less. Lower the quality, not the pixels, so the face stays clear.
- Scan the signature on white paper and keep it under 30KB. The phone signature scanning guide shows how.
- Scan each certificate as one clear file and shrink it under 200KB. See how to compress a PDF to 200KB if the file refuses to shrink.
- Create your APAAR or ABC ID if you do not have one, using the APAAR ID download guide.
If the upload fails
The commonest cause is a file a few KB over the limit, so check the size in file properties before you pick it. A scan that is too dark to read is the next one, so open each file once at full size before uploading.
The limits above are the ones printed in the decentralised counselling notice. If another university sheet or a different counselling round gives other figures, go by the notice for the form you are filling.
If you cannot apply online, a physical form in the prescribed format goes to the UCSTA office at Rajabazar Science College Campus, 92 A.P.C. Road, Kolkata 700009 by 2:00 PM on 27 October. It can also be emailed to the helpdesk.
Checklist before you submit
