10 very common Edexcel 9-1 IGCSE Biology exam questions. Paper 1B.

Quick links:
01:23 Movement of substances
02:41 Arteries vs veins
03:25 Gas Exchange
04:41 Absorption in the small intestine
05:18 Genetically modified bacteria
06:18 Designing an investigation
07:56 Stating variables
09:32 Reliability of results

These questions are all based on paper 1B of the Edexcel IGCSE 9-1 course, which is for both double award and triple award students. Obviously, lots of IGCSE Biology courses are very similar, so it’s probably useful to most students even if studying a different specification.
