About this calculator
The School Grade Calculator computes the simple arithmetic mean of four bimonthly grades, common in the Brazilian education system. Simply enter the grades for each term and click calculate to get the result. This tool is useful for students, parents, and teachers who want to track academic performance throughout the school year.
The calculation is done by adding the four grades and dividing the total by four, according to the formula: average = (N1 + N2 + N3 + N4) / 4. The result is displayed with two decimal places. Note that this calculator only considers the simple average, without weights or recovery exams, suitable for institutions that adopt this model.
Use this calculator to check if you have reached the required average for approval, simulate improvement scenarios, or plan your studies. For example, if you have grades 6, 7, 5, and 8, the average will be 6.5. If the minimum passing average is 7, you'll know you need to improve next term.
Caution: this calculator does not replace the official report card. Verify with your school if the grade calculation follows exactly the simple arithmetic mean, as some institutions use weights or recovery systems. Always confirm the approval criteria with the pedagogical coordination.
