True. Questions shouldn’t be open ended and should be as specific as possible.
Obviously studying with MCQ is better than not studying at all. I was just arguing that proper active recall questions are much better for learning things, while proper MCQ are much better at testing what you know or understand about the topic, after the learning phase already happened. The premise of OP regarding the scientific “facts” were just wrong, which I felt like should be pointed out.
So if it would be studying with MCQ vs not studying at all, then MCQ clearly is the better option. Or if studying for exams is the primary goal and long term retention isn’t as important, MCQ works as well.
What do you need help with? Just the design of having a flashcard on a desk? If you open a new topic I’d probably be able to help you.
