I think it would be really helpful have subtopics for each System. For example: Having a dropdown for Endocrine System with subtopics such as "Thyroid Pathologies", "Hypothalamus Pituitary Pathologies", "Adrenal Pathologies", "Metabolic Disorders", "Parathyroid"c etc. 

An account dashboard feature to track the # of questions you have answered in a given period of time. For Example from mm/dd/yyyy-mm/dd/yyyy = 1234 questions answered. As a specific example I wanted to know how many questions I have answered in the 4 weeks leading up to my test, but it would also be useful for 6 weeks out to see where I started versus ended up just by sheer gross numbers.

Add an option under create an exam that allows us to filter questions for this test by Question ID number.  Also, allowing separate search criteria separated by commas under, "Search Question", would be equally as useful.

Please create a feature to change the time per question in timed exams for those of us with accommodations. This would allow us to have a better representation of the test-day experience. Maybe add a button where the timed exam can be switched to "1.5x" or "2x" time. Thank you

Goal Percentile feature to help keep track of where you currently are compared to a stated and flexible goal

I'm routinely doing things like starting an exam with only 1 question because I forget to edit the number. I think it would be nice to be able to make a default setting so that you can start a frequently used exam with one click.
