Foundational C# final exam successful but can't see my mistakes

I can bring up my results that show 76 correct answers out of 80 but can’t see which ones I got wrong. I need to know which 4 questions I got wrong so that I can take a closer look and figure out what I missed. Has anyone been able to?

I am not sure if this is intentional or not, but from a student’s perspective this is totally unexpected: what is the point of a graded assignment if I can’t learn from my mistakes?
