IB Computer Science Grade Boundaries

Computer Science Grade Boundaries

View IB Computer Science grade boundaries over time for HL and SL. Understand score trends and how marks convert into final IB grades.

Grade boundaries explain how raw exam marks are converted into final IB grades from 1 to 7 and are adjusted each session to reflect exam difficulty and global student performance.

By reviewing grade boundaries over time, students and teachers can better understand expectations, identify trends, and set more accurate performance targets.
