Basic weighted grade formula
Place grades in one column and units or weights in another. Use SUMPRODUCT for weighted points and SUM for total units.
GWA formula in Excel
If grades are in B2:B8 and units are in C2:C8, use =SUMPRODUCT(B2:B8,C2:C8)/SUM(C2:C8).
DepEd component scores
For written work, performance tasks, and quarterly assessment, convert raw scores to percentage scores first, then multiply by the assigned component weight.
