Roll up each student's final-exam total into a PASS or FAIL for the year.
Go to Year results, pick the academic year + grade + section, and click Load class. The roster appears with each student's total and percentage from the FINAL exam.

Click Auto-fill from marks — every row gets PASS or FAIL by the pass threshold. Adjust individual rows and add remarks as needed.
Click Save year results to write the result for the class.
Do this before promoting students, so the roll-up decides who moves up.
