Unattempted questions from sectionals, mocks: Mask the answer before revealing it with a button.

suggestion for mock analysis: please do not reveal the answers to unattempted questions from mocks, sectionals and topic tests on the get-go. it would be really great if like practice questions, you can mask the answers, to be revealed by a button like "show answer". it would be really great for practice, if, after the mock, during the analysis, we could still try to attempt the question on our own, to test our knowledge.
