Randomized question order
Removed answer choice 0 in exam model bc it was showing A as the answer choice for every question. Set the choice field to a default value of 0 in a migration instead.
Added exams.css to dashboard css. Fixed styling so answers do not waste a line while wrapping
Fixed legend styling and scrolling on question change
Using full_name instead of name in views when referring to a bank now. For example, "Internal" will be displayed as "Internal Medicine"
Added loading spinner to exam images
