Part 1: French Baccalaureate (Bac) Score Calculator (Global Focus)

What is the French Baccalaureate?

The French Baccalaureate (le Bac) is a national secondary school leaving examination taken by students in France and in French international schools worldwide. There are over 500 French accredited schools in 139 countries, including the UAE, USA, Canada, UK, Australia, and across Europe, Africa, and Asia. A Bac Calculator helps students predict their final score based on continuous assessment (contrôle continu) and final exam results.

Why Use a Bac Calculator?

A Bac Calculator is essential for:

Estimating final Bac scores before official results
Identifying subjects that need improvement
Determining the minimum final exam score required to achieve a desired mention (Passable, Assez bien, Bien, Très bien)
University applications in France, Europe, and globally
Tracking academic progress throughout Première and Terminale

French Baccalaureate Grading System (Worldwide Standard)

Mention	Average Score (/20)
Très bien (Very good)	≥ 16
Bien (Good)	14 – 15.99
Assez bien (Fairly good)	12 – 13.99
Passable (Pass)	10 – 11.99
Échec (Fail)	< 10

A Bac Calculator converts raw subject scores into weighted averages and mentions.

How to Use a Bac Calculator (Step-by-Step)

Gather your continuous assessment grades (Première and Terminale) with their coefficients.
Enter each subject’s grade (out of 20) into the Bac Calculator.
Enter the corresponding coefficient (coeff) for each subject.
If final exams are completed, enter those scores.
Click Calculate – the Bac Calculator displays:
- Weighted average for contrôle continu
- Weighted average for épreuves terminales
- Overall Bac score (/20)
- Mention

Practical Example (General Bac)

Subject	Coefficient	Grade (/20)
