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?

Restricting the possibilities for the first two questions to only those pairs not mentioned assumes that nobody got the first two right.  That's not implied by the fact that somebody got them all wrong.
