This post starts with a massive proviso of course. Making predictions as to which topics might appear in a future exam is a very risky business. The paper 2 you will all sit after half term can test material from the entire specification (including all the specification points in bold) and there is absolutely no guarantee that topics tested in paper 1 may not reappear in some form in paper 2.
So the proviso is this: the only way to be fully prepared for paper 2 is to revise the entire specification so that you are prepared for whatever the examiners might throw at you.
But having said that, it seems sensible to focus your revision for paper 2 onto topic areas that were not examined in paper 1. If I were in your position, these are the topic areas for which I would be doing most of my revision in the coming weeks:
- Respiration 2.33 – 2.37
- Gas exchange in Plants 2.38-2.43
- Transport in Plants 2.49 – 2.56
- Transport in Humans 2.57 – 2.66
- Kidney 2.68 – 2.76
- Reproduction 3.1 – 3.12
- Food Chains and Energy Flow 4.4 – 4.7
- Nitrogen and Water Cycles 4.8, 4.10
- Human Influences on Environment 4.11 – 4.17
- Food Production (including fish farming) 5.1 – 5.9
- Selective Breeding and Genetic Modification 5.10 – 5.16
The bad news is that this list above still forms a large proportion of the extensive EdExcel IGCSE Biology specification but the good news is that there are PMGBiology blog posts on all the above. So please use the search function on my homepage to find material to help you revise.
Practice papers and mark schemes are available online (and for my students on the school Firefly page)
Keep working hard – you are almost there and the summer to come will be long and restful….
