Memory tip (Patterns beat cramming): Smart: know what each letter is, see where it comes from, use it in a few sums, a formula card, test yourself weekly. Weak: copy it 50 times blindly, cram it the last night, never use it in sums, skip what letters mean. The 9s trick: for 9 × n, the tens digit is n − 1 and the ones digit is 10 − n: 9 × 7 → 6 and 3 → 63.
