In the MC II-B Counting & Probability Guided Study Group for Summer 2020 course, it says that "You should receive an email (to the email associated with your account) with information about how to access the eBook." However, I did not get any news or emails about how to access the textbook or eBook. My email is andrewm17us@gmail.com, and it was the same on my profile, so I don't know why I didn't receive it. How do I access the eBook then?
