Five students each answered five questions on an quiz consisting of two multiple-choice questions (A, B or C) and three True-False questions. They answered the questions as follows:
Student Q1 Q2 Q3 Q4 Q5
Alex A A T T T
Bert B B T F T
Carl A B T T F
Dave B C T T F
Eddy C A F T T
No two students got the same number of correct answers. Who got the most correct answers?

I agree - no one could get 5 right answers. So, the answers to the first two questions could have been AC, BA, CB or CC, and the answers to the last three TFF, FTF, FFT or FFF.
Unless I get a brighter idea, checking these 16 (4x4) combinations would find the answer, with no special reasoning involved...
