Know more about Chemistry HL vs SL. IB Chemistry HL extends far beyond the SL syllabus, covering additional topics in greater depth and with more complex calculations, making it a substantial step up in commitment.

Major HL Extensions Beyond SL:

  • Additional Topics: HL-only units on Acids & Bases, Bonding, Energetics, Kinetics, and Organic Chemistry.

  • Depth: SL topics are revisited and extended (e.g., equilibrium calculations are more advanced in HL).

  • Options: Both choose one, but HL options require application of deeper knowledge.

  • Internal Assessment: Expectations for design and analysis are higher at HL.

  • Exam Papers: HL has more questions and longer papers, testing the extra material.

HL Chemistry is essential for medicine, chemistry, and chemical engineering degrees.
