Stored equation:
Grade = (100/Q)*(Q - M) + (100/Q)*(76/100)*(W - TP) + (100/Q)*(60/100)*S + Σi=1..TP[ (100/Q)*(BCRᵢ/PQᵢ) + (100/Q)*(76/100)*(ACRᵢ/PQᵢ) ]
Variable key: Q = total questions, M = mistakes, W = written fixed, S = static fixed, PQ# = partial questions in module #, BCR# = correct before retake, ACR# = correct after retake, TP = total partial modules.
