Edexcel IAL Biology questions

EduNinja's AS context maps to the IAS Units 1–3, while A2 maps to the IA2 Units 4–6 used to complete the International A Level.

Yes. The qualification is organized into six externally assessed units rather than a single linear exam route.

The IAS and IA2 stages contain different units, syllabus scope and assessments, so selecting AS or A2 keeps every resource URL unambiguous.
