IB DP Biology SL
Biology SL is the Standard Level course for Biology. It covers molecules, cells, genetics, evolution, ecology and human physiology, with practical investigation.
Standard Level (SL) courses cover the essential content and skills in roughly 150 teaching hours, giving a solid foundation without the added depth and breadth of Higher Level.
What students will do
- Master core content and terminology
- Design and analyse experiments
- Evaluate evidence critically
Internal assessment
Students complete an independent scientific investigation, which contributes to the final grade alongside the external exams.
Revision tip
Link every fact to an everyday example. Ideas you can connect to real life are much easier to remember and apply.
Should I choose HL or HL?
Choose HL for subjects you enjoy most or may study at university, and SL for the rest. Your teacher or DP coordinator can advise on the right balance.
