When studying with multiple choice or flashcards you can click the gear in the top left to configure your current study session. Here is what each of these options means:
Reverse - Toggles whether you are prompted with the term or fact side with the term or fact. This is useful to help make sure you know your content forwards and backwards
Goal: Master all facts - This goal uses spaced repetition to help you incrementally master each fact, denoted by the colored progress scores. The mastery levels are Beginner (60%), Intermediate (70%), Advanced (80%), Expert (90%), and Genius (100%). Memorang will pick only certain facts to test you at a time, and when you master one portion of the content it will move on to other items you haven't seen yet. We designed the system this way because it's the most optimal manner by which to tackle large volumes of content.
Goal: Complete all facts in order - This goal simply asks each fact once in the order it was written. Great for getting a quick first pass of the study set (or reviewing something you've created) but not highly recommend to be used long-term.
Goal: Complete all facts in shuffled order - This goal will lead you to answer each fact once, but the order will be shuffled before you begin.
