The difference between IB Physics HL vs SL is significant in scope, depth, and mathematical sophistication, not just difficulty. HL contains all SL content plus additional higher-level material.
Key Differences:
-
Teaching Hours: SL = 150 hours, HL = 240 hours.
-
Syllabus Size: HL has approximately 60% more content, including entire additional topics (e.g., Wave Phenomena, Fields, Quantum Physics).
-
Mathematical Rigor: HL requires more advanced calculus and problem-solving.
-
Option Topics: Both choose one, but HL options are more complex.
-
Assessment: HL has an extra Paper 3 focusing on the option topic and data analysis.
Choose HL only if required for university (engineering, physics) and if you have strong math skills and a genuine interest.
