why system display incorrect Combination Exam Result Status enquiry?

According to particular student result status as “Fail” is because he/she has failed of the school exam for subject. In the other hand, The “Final Exam” (Combination Exam) Parameter setting have been set to “All Sub-Exam/Test taken are compulsory pass” at the “Subject Status and Credit Earn” parameter. Therefore, you need to set it to “Relative to no. of sub-exam/test taken” and re-run the produce class/level ranking then our system will get the Result status base on the subject final exam marks.
