How a SQL match works

  1. Seven rounds. The same seven SQL questions for you and your opponent.
  2. Ten seconds each. A right answer in two seconds scores 20; at the buzzer, 11.
  3. The last round counts double. It’s never over until it’s over.

Your SQL ranking is its own: climb it without your other topics dragging you down.
