First off, let me say that your Roundup application is absolutely fantastic! It has really helped me pinpoint the areas I need to concentrate on more before hitting the certification exam. I would like to request a small change to the program: Allow the person, after completing 3 rounds, to choose whether to only view incorrectly answered questions or all questions. Sometimes I get a question right by knowing part of it and I'd really like to refresh my memory on why the other part is correct. i.e. The question is "True or False? [Part A of the question] and [Part B of the question]." I might know that Part A is false and thus the question is false, but a little reminder as to why Part B is true or false would be nice. Again, many thanks for your wonderful application!
