Hi @Vanessa Allen,
Thank you for reaching out! Luckily to begin your CDA with CLASS Course, you do not need a Product Key or your book. You will log into your account by going to teachstone.com and selecting login in the upper-righthand corner. On your main dashboard, you will select "Learning Hub" to access your course. If you have any other questions, you can chat with our Customer Support team via the "chat with support" button in the lower right-hand corner of the screen when we are online, or by emailing us at contact@teachstone.com.
I hope this helps!
Best,
Allison
