FAQ

What background does the CET-4/6 photo need?
Blue or white are both acceptable — follow your current registration notice. Light sky blue #CCE9FC and standard blue (#438EDB) are each accepted by some systems.
Why must a CET-4/6 photo be under 10KB?
Some university or regional CET registration systems use older upload components capped at 10KB. The requirement is met by lowering JPEG quality (not by shrinking dimensions) while keeping facial features clear.
