Is it mandatory to submit official transcripts or will mark sheets for all semesters suffice for university applications in UK/Ireland?

Yes, official transcripts are generally mandatory for university applications in the UK and Ireland. Mark sheets alone usually do not meet the requirements.

- Official transcripts are certified documents from your institution listing all courses, grades, and degrees. Universities require these to fully assess your academic history.
- Mark sheets may not provide enough detail and are typically not sufficient on their own.
- If your transcripts are not in English, a certified translation is usually required.

Request your official transcripts from your institution early, as processing can take time.
