What this buys you on test day

If 3x² = 507 and x > 0, what is x?

Computing it~35s
  1. 507 ÷ 3 = 169
  2. Try 12² = 144, too small
  3. Try 13² = 169 ✓
  4. x = 13
Recalling it~8s
  1. 507 ÷ 3 = 169
  2. 169 is 13²
  3. x = 13

Knowing 13² = 169 cold saves about 27s here. Hit 12 moments like it in a section and that is 5 minutes back for the questions that actually test reasoning.
