Everyone who is using/used Marrow QBank, how do you use those three kind of bookmarks?
For me Ribbon means I’ve studied but did silly mistake, Star means studied but concept is not clear, Question mark means never heard of this in life.

Use the question mark one for extremely important topics / never heard topics but important . Use the star one for silly mistakes / mistakes in topics you know . Use the ribbon one for rest of the clutter .

Ribbon if thr explaination is good or has images ( only corectly responded qs)

Star for wrong ones

? For topics not in notes or never heard of
