Hello,

Hi all,
Please help me.

1. find out the results average, mean, highest and lowest score from the Overall marks.
2. Match these same results to the different types of Genre tests.
3. Be able to find out which tests are harder to pass, and the average per test.
4. If possible I would like to be able to compare test 1 to test 2
I am using excel 2003
I have put the files online and here is the password if it is needed.
