Leitner System

I was just wondering if you could provide detailed explanation of how the "Cram"/Leitner system works in Mental Case. Does it use a 2 box system or is it the traditional 5? After I run through a set of flashcards, should I press update due status or is that something else?

Also if possible could explain the other study schedules. I know in the mac app it gives a little summary, but I want to make sure I really understand how each system works so I can choose wisely.

Thank you!

    Also, I was wondering if you could add the option to repeat cards through out the slideshow on the mac version like you have on the old ipad app. I know right now it repeat shortly after, but when it repeats a lot (4x) it helps me remember a lot more than seeing it once shortly after and at the end. I find myself returning to that app so I can have cards repeat several times. I know you've decided to implement these successful learning algorithms, but just having "repeat throughout" as an option would be wonderful.

    Hi David,

    At the moment, Mental Case 2 will repeat a note up to 2 times in the current slideshow, but it also allows you to start a new slideshow with just the wrong notes, so you can probably achieve what you want without any new features. Just start a new slideshow at the end, and include only the wrong notes.

    The details of the learning schedules are complex, and we deliberately don't go into great detail. We want the tool to be accessible to all students, not just people into geeky flashcard systems.

    Cram is based on Leitner. There are 5 boxes. Cards start in the first box. If you get them right, they move to the next. Get one wrong, it goes back to the first box. The system shows you the notes that are in the lowest occupied box.

    Cram is the only system that is not time based in Mental Case. You can just refresh your due notes to get some more due notes. That is how it is intended to be used.

    The other systems all have a time element. The standard one is Long Term learning. It is based on Supermemo's algorithm (http://www.supermemo.com/english/ol/sm2.htm).

    We have standard time intervals, but these intervals are adjusted based on how well you answer a note. Answer wrong a few times, and the intervals for that note shorten to help you out.

    The date targeted schedule is unique to MC. It is basically the supermemo algorithm, but it dynamically adapts to try to ensure a certain likelihood of recall on the day you target (eg exam).

    Think they are the main ones.
    Hope it helps.
    Kind regards,
