Think back to the last college exam you took and think of

Think back to the last college exam you took and think of the exam as a psychological measure. What construct do you think it was intended to measure? Comment on its face and content validity.  What data could you collect to assess its reliability and criterion validity?

I have taken several college exams some was multiple choice other was written are both multiple choice and written combine. The most recent one was a multiple choice. In which the points value total 100 percent. The time limit to complete the exam was 6 mins.
