IF COUNTIF- To Determine That If A Range Of Cells Are Marked With An "X"

I am trying to determine that if a range of cells are marked with an "X", then cells containing "Pass" (A4), Pass with Opportunity for Improvement (A6)or "Fail" (A8) will be marked with an "X". I have 3 columns that are selectable for Pass, Fail, and Non-Applicable. There are a total of thirteen questions that this evaluation form asks, and the evaluator must check one box. In order to be considered a Pass, there must be more 12 or more "X"'s marked in the Pass column. A Pass with Opportunity for Improvement would be equal to 11 marked in the Pass column, and a Failure would be 10 or less showing up in the Fail column. If there is a check in the non-applicable section, this has to be figured into thye pass fail as well. A Pass would be 85% or higher, and failure anything less than this. I will attach the file for review. I would very much appreciate help on this problem first, and then there is one other element to the sheet that plays in at the end.
