Hey,

Usually the marksheet states the purpose it's fulfilling. The information regarding the exam is mentioned on the marksheet itself.

So I believe the supplementary marksheet will be written on the Marksheet.

For more clarification you can be in touch with your Senior who has given then Supplementary exam. But I believe supplementary will be written on your marksheet and that will show that you are a repeater.

Hope that helps.

Thank you.
