Tips
Mark these like a marker, not like a student. The schemes list separate points, and the gap between "I said roughly that" and "I said the point" is where most marks go. Highlight the exact words in your answer that earn each point — if you cannot find them, you did not earn it.
Collect the command words as you go. Across a few papers the same verbs attach to the same kinds of question, and knowing which one wants a mechanism is worth more than another pass through the content.
The practical papers test experimental reasoning, not recall, so you can attempt them early, before you have finished the content. Doing them alongside the theory also fixes the vocabulary faster, because you have to use it.
