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?

Q1-B, Q2-C, Q3-T, Q4-F, Q5-F This means Dave got the most correct answers with 4 correct. I confess. I solved this with trial and error or a brute force method as has been called. Unless I overlooked one, I think this is the only one.
