Hamstudy should track practice exam scores towards an exam date that the user can specify. This can be used for a graphical display of what a projected score might be if the user continues improving at the current rate.
This can be used to encourage users to study more, or to give them confidence in the material they are learning. Please see attached mockup for a possible graphical display. Changes are in red.
In addition to the graphical display, a text notice might be useful in the header, giving a "countdown to exam", and a "projected score". Appropriate caveats should be used to warn the user of the risk of overconfidence and relying on this projection too much.
