I, too, have written all of the optionals. My take is that I would like every app to be successful. A school isn't a very good backup if I get rejected. My goal is to make each application as good as possible. Period.
Which LRs are real? I got three 25 questions LRs. One with social experiment, one with question like smth is necessary for success, but one with smth is not successful so smth is not necessary for success. Really blurr memories.
