Mancosa not the best at all failed wrongly just to pay again the school fees

Mancosa not the best at all. I have done by exam which i passed and did the assessment and pass it but now i got notification that i failed got 49% and both exam and assessment i passed more than 50%. I have done the other 5 subjects had no issue and even got less marks for them but i passed all 5 now accounting which i got 50% i was told i did not meet their criteria. Mancoss we always do assessment and exam not i only told i was suppose to do 3 assessment which i dont know anything about student number 162488
