THE SOLUTION:
Ham scored the A, followed by Pam with the B, Sam with the C, Tam with the D, and Cam failed with the E.
One possible logic sequence:
Clue #1: Skip for now.
Clue #2: Cam <> A or B, Sam <> A or F, and Pam <> D or E.
Clue #3: Either Pam = A and Tam = E, or Pam = B and Tam = D.
But Tam =Â E does not work, since (refer to Clue 1) that would mean that no boy scored the C, and one of them had to.
So Pam = B and Tam = D, forcing Ham = A, which forces Cam =Â E and then Sam = C.
