DP Design curriculum is changing starting in the Fall of 2025 and after. Major changes are listed below.
Updated HL content is focused on Structural Engineering, Mechanical Engineering, and Electronics Engineering (much more physics and engineering-based)
SL content is very similar to what it was- product design theory.
The IA project is now the same amount of time for BOTH SL and HL (same hours, slightly different weighting: SL = 40% of overall grade, HL = 30% overall grade).
There is no more Paper 3 test (long answer test questions for either SL or HL). Only Paper 1 and Paper 2 questions for both SL and HL students.
