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?

Reached a block.... :(

By this method i could only figure out that none of them answered all the questions right !!!

So 1 ( and only 1 ) of them has all questions wrong !!!

Does it help to know this ???
