Oh yeah don't worry, I'm most concerned about Physics too, its just full of stuff I'm not bothered about tbh.
The topics that are most likely to come up are:
-Extraction of DNA (experiment)
-Enzymes
-The Human Genome Project (never come up)
-Mitosis and Meisos (comes up every single year)
-Cloning Mammals (not seen much on it)
-Stem cells (not come up much)
-Plants (exam board loves them so comes up all the time)
-Evolution and Fossils
-Distribution of organisms (never seen)
-Genetic engineering
- Heart and Digestive system (exam board loves these)
-Functional foods
That's about it I think, yeah that's a lot but we gotta work our arses off now, good luck xo
