Simple memorizer is a lightweight web application that helps to efficiently memorize any question-answer sets.

How it works

  • user registers and logs in via oAuth2 services: Facebook or Google
  • any user can create arbitrary number of courses, course is a question wrapper
  • any course can contain arbitrary number of questions provided by the user, question is a key-value pair
  • while working in run mode system ask questions from particular course
  • user clicks "Good" button if they know the answer, "Bad" if not or "Show answer" to show the answer
  • there is no need to provide the answer in any way, user doesn't have to prove he knows it
  • the more times user will mark particular questions as well known, the less they will be asked
  • analogously, questions with more wrong answers will be asked more often

Points rules

  • default question points value is 10
  • every good answer decreases points by 1
  • every wrong answer increases points by 1
  • questions with just one point are considered as well known
  • course average points value is recomputed at every points change
