Hi,

It seems you must be asking about 'RT' which mentioned on the result marksheet. You must have got 'RT' in one the examination paper. 'RT' means reappear in theory. So, it means you have to reappear again for the theory paper for the said subject when the examination will be held again.

Hope, your query is answered. You can write in the comment section below if it is any other term or please restructure your question.
