Kindly clarify how is grade points and total grade points computed for the following case
Marks in a subject (For example)
FA #1 : 84 out of 100
FA #2 : 93 out of 100
SA #1 : 75.5 out of 90
FA #3 : 87 out of 100
FA #4 (PSA) : 52 out of 60
SA #2 : 82 out of 90

Kindly tell me what will be the grades in each assessment and what will be the total grade? (Just for understanding the concept)

With regards
