Is it possible to use correcting fluid on an OMR sheet?
You can use correcting fluid on an OMR; however, due to it being checked electronically, mostly, you will not get desired outcomes. I would suggest you use pencil to initially mark your answers which you are not sure of and before marking any answer with pen check it at least 3 times. Keep practicing on OMRs. That way, you are less likely to make mistakes.
