How to Calculate Class Sections
Determine how many sections are needed to serve all students within size limits.
Formula
Sections Needed = ceil(Total Students / Max Class Size)
Average Size = Total Students / Sections
Rounding up ensures no class exceeds the maximum.
Example Calculation
150 students need to be placed in classes with a maximum of 30.
- 01Sections needed = ceil(150 / 30) = 5
- 02Average class size = 150 / 5 = 30
- 03Empty seats = 5 x 30 - 150 = 0
