Earlier design would place a Next button in the feedback encouraging the student to click that and move on. Current design has a single Next button whose branch changes after getting feedback. Problems occur if student chooses an answer, gets feedback with branch but instead of pressing Next they pick another answer. Now hitting Next takes them to the first branch which can be confusing.
Technically their only option after the first answer should be Next. Perhaps disable all answer buttons (a,b,c, "Grade", etc.) Disable buttons can be puzzling. Maybe treat the feedback with Next like a modal. Somehow gray out the entire question and answers except feedback text and Next?
