Tips
Split these papers by half. Theory questions suit short, frequent sessions — they test recall of precise definitions, and precision decays fast. Programming questions need long, uninterrupted sittings, because the skill is holding a whole solution in your head.
Write the code by hand, then type it in and run it. Past papers are the one place you can discover that what you "would have written" does not compile — much cheaper to find out now than in the exam hall.
When marking theory, compare your wording to the scheme word by word, not by meaning. This subject's schemes are unusually literal, and the right idea in the wrong words often scores zero. Keep a list of the phrasings you keep missing.
