HOW TO CALCULATE STUDENT AGGREGATE

[peterappiahkubi]

In creating an excel app to calculate the aggregate for students in their exams as used by WAEC to determine the student aggregate in BECE . The Excel has to select Six Subjects from ine Subjects, with Four being compulsory and Two other best I want an excel formular that will add the grade value of four compulsory subjects : English, Maths, Science, Social. And then automatically select 2 other subjects from the rest with best grade value.

For Instance, If a student has the following result:
1. English - 2
2. Maths - 1
3. Science - 1
4. Social - 2
5. ICT - 3
6. BDT - 3
7. RME - 1
8. French - 2
9. Twi -

I want a formular for this calculation :
English(2)+Maths(1)+Science(1)+Social(2) and randomly select best other two subjects from the rest : RME(1)+French(2) = 10

Kindly help me.

=SUM(B1:B4)+SMALL(B5:B9,1)+SMALL(B5:B9,2)

=SUMIFS(Grade,Type,"Compulsory")+MINIFS(Grade,Type,"Other")+MINIFS(Grade,Type,"Other",Grade,">"&MINIFS(Grade,Type,"Other"))
D5	D5	=AGGREGATE(15,6,Grade/((Type="Other")*(Grade<>"")),2)+AGGREGATE(15,6,Grade/((Type="Other")*(Grade<>"")),1)+SUMIFS(Grade,Type,"Compulsory"
