Hi Fenna E! I apologize for the inconvenience. Thanks so much for reporting this. This should now be fixed! Please let us know if you continue to run into any issues!

I decided to try the training myself. I'm also stuck at the same spot, looks like a bug to me. The UI makes you select 4, and I can't find a combination of 4 that works.

May be same issue reported in https://schoolhouse.canny.io/bugs/p/sat-boot-camp-training-question-not-working. And if so, that submitter indicated you had to pick 4 choices, so me saying to unselect C wouldn't help. The user that submitted that bug is going to chat with support next (dropdown at top right of Schoolhouse, Chat with Support).

Fenna E have you tried leaving choice C unchecked? You may have a different guide than I'm familiar with, but I'm not aware of it being advised to ask them why they missed a session (not mentioned in https://schoolhouse.world/faq/en/articles/9961216-what-do-i-do-if-a-learner-misses-my-session). B, E, and F look good to me though.
