How is the weighted average calculated?

Each subject's mark is multiplied by its coefficient, then the sum of (mark × coef) is divided by the sum of coefficients. Example: a subject at 14 (coef 3) and one at 10 (coef 1) → (14×3 + 10×1) ÷ 4 = 13.

What's the pass threshold?

A pass is generally from 10 out of 20. Mentions: pass from 10, fairly good from 12, good from 14, very good from 16, and excellent from 18.

Does the tool include official coefficients?

No, you enter the coefficients yourself since they vary by stream and level. This makes the tool work for any system (bac, LMD, grandes écoles…).

Yes, marks are out of 20 (clamped between 0 and 20). The coefficient is a positive number.
