Converting units Quiz

How it works

• 10 questions, about 20 minutes (a timer counts down; you can hide it). Solve it right here: no sign-up.
• 0 questions have choices. For the others you type the answer: a number like 4, −2, 7/2 or 3.5, or for example x = 4, x = 2 or x = −3, (3, 5), 2x + 1. Use ^ for powers (x^2) and sqrt for √. Any form with the same value counts (7/2 = 3.5).
• One question at a time: Back, Next, Mark for review and the question list at the bottom. No calculator: work it out on paper.
• At the end: your percent and grade, every question right or wrong, why a wrong choice is wrong, and its step-by-step solution. Then practise the lesson with new questions.
