You can check on your dashboard by clicking on the blue button that I have talked about earlier, which will take you to your challenge page. When you're on this page, click on "make challenge" and fill out the fields below. Then, go back to your dashboard and click on "start a new challenge". Then fill out the fields again and submit.
After this has been done, go back to course hero and click on "my challenges" where you will see all of the challenges that have been completed.
After this has been done, go back to course hero and click on your avatar where you will see your avatar on the top of the page.
