Please sir, I listen to the webinar organised by ACCA and the tutor said we can write all the answer is capital letter, that it will be more eligible if ones handwriting may not be clear; please can we answer in capital letter.
Yes you can (otherwise the ACCA would not have said that you can!!).
The only downside is that it takes longer to write everything in capital letters.
Write something out normally and give to to a friend or someone to read and see if they find it easy to read. If they can’t read it, then maybe consider writing in capital letters.
