Here's what I'm trying to do:

1 Test Question 1 2 3 4 5 6 ...
2 Answers Key A C A B D B ... # of Right Answers
3 Student 1 A D A B D C ... 4 (Formula would go here to compare current row)
4 Student 2 A C A B D D ... 5 (with Answer Key row & count the right answers)
....

How do count the right answers by comparing the answers from each student with the Answer Key in row 2. I want to be able to score the tests by entering in the answers.
