CS Countdown

Race against the clock to answer Computer Science questions. The faster you answer, the more points you earn.

How it works: Each question has a countdown timer. Type your answer and submit before time runs out. Your score for each question equals the seconds remaining when you answer correctly. Need help? Use the hint button, but it will halve your available points. Skip a question to move on with 0 points.
