Can I improve my quiz score?

You will earn 10 points for every graded quiz question you answer correctly, but you can only earn points the first time you attempt to answer them. Going back and answering quiz questions again will not change your score.

The only way to improve your score is by resetting your progress and taking all the lessons again. 

If you would like to start the entire program from the beginning, you can reset the program, but doing so will erase all of your progress, and this action cannot be undone.

To reset the program, you can follow these step by step instructions from the How can I reset my progress? guide.
