Biology - cloning was a 6 mark question, fossils and reasons for evolution - look at pentadactyl limbs and why they're helpful that was the other 6 mark question, mitosis and meiosis, the heart make sure you know the circulatory system and the organs and the ways blood enters and leaves the heart, red blood cells and why they shouldn't have a nucleus, structure of DNA, anaerobic respiration, protein synthesis the second half after transcription, plants and parts of a leaf and genetic engineering of animals helping human research.
Chemistry - definitions of isotopes and catalysts, graphite and diamond structures, formation of water molecules compared to sodium chloride or something so look at those formations and features - it's a 6 mark question, calculating empirical formula, isotopes and relative atomic mass, balancing equations, alkaline salts including insoluble ones, properties of metals, flame test colours, reactivity of alkaline metals - 6 mark question, and know exothermic and endothermic graphs and the collision theory.
Basically every single question that came up ^ our physics exam is tomorrow so we haven't done it yet good luck!
