or is it 2 early… thoughts?
Sure why not. It’s better to use the feedback for allocating review time among topics.
i would advise your against doing it until you finish all your materials, but that’s just me. i think you’d know even without having to take the mock exam where your weak areas are. personally i think it’s wiser to spend that time reviewing more materials. at least i learn tons more from reading than brute force doing 100000 Qbank questions and learning that way. but that’s always been my learning style.
