I cannot log in!

If your instructor integrated Accepi into your learning management system (e.g., Canvas, Blackboard), you don't have a password and don't need a password. Log into your LMS and click on the link to Accepi. However, if your instructor provided you with a registration link in the past, you need to log in at If you cannot remember your password, reset it here.

How do I change my password (if you don't access Accepi through your LMS)?

If you still know your password, log in and click on "My account" (top right) and choose a new password. If you don't know your password anymore, reset it here.

How can I join my professor's course?

Follow your instructor's instructions: either log in through your learning management system (e.g., Canvas or Blackboard), or use the registration link handed out by your instructor. The link should look like, but with a different token at the end.

I've dropped the course. How can I get a refund?

You can request a refund within 20 days of payment by emailing us at with your name, email address and the course for which you request a refund.

How do I submit a homework assignment?

All your work is submitted automatically as soon as you submit an answer.

Your rounding is ridiculous. What's going on?

Your instructor sets the answer tolerance. The default is 2%, i.e., any submitted answer within 2% of the correct solution is accepted. Our intermediate calculations are not rounded, but the number of decimal places displayed is limited (you wouldn't want to look at numbers that all have 64 decimal places). If in doubt, use more decimal places in your calculations.

Your solution is wrong. How can I get my points back?

Make sure your answer is correct by comparing your approach to the solution. Make sure that you didn't round any intermediate results used to derive your final answer. If you still think that our solution is wrong and yours is right, click on the flag icon and explain why you think our solution is wrong. If you're right, we will give you full points for that part.

What happens when I click on "See solution"?

You will see the solution for that part and can then try the part again with different numbers to earn the remaining points for that part. Depending on your instructor's settings, you may lose some points for requesting to see the solution.

What happens when I click on "Practice again"?

You can practice the problem again with different numbers. It will not affect your recorded points or your assignment score.
