Is the BMAT exam digital and will there be any rough sheets or formal substitution allowed during the test?

No, the BMAT exam is not digital - it is a pen-and-paper test.

You will not receive separate rough sheets, but you can use the question paper itself for rough work, including calculations, notes, and diagrams. No digital devices or calculators are allowed during the exam. Formal substitution is not specifically mentioned, but you may use the exam paper for any necessary workings.
