I posted this on another thread, but here goes....
This is a link to the TESC catalog, I can't attach the catalog or even the 2 pages where this information is because it's too large (3mb). Here's a link to download it and this information is on pages 120-121 of the document:

The only thing they don't specify (or at least I didn't find it) is what letter grade is assigned, if any, to each exam. Only the passing score is shown.
