How do stars, crowns and experience points work?

Experience points, levels, stars and crowns are designed to help you measure the progress of your learning in a fun, gamified way and help you stay motivate to learn.

Experience points

Experience points reward pure effort. Every time you take (or retake a quiz) in the Oxford Revise App, you gain experience points equal to the points scored for the quiz and your experience points score at the top of the app will increase. You can receive up to 200 points for each question you answer and so up to 4,000 more points each time you take a 20 question quiz. If you retake a quiz you will always get the new points for that quiz attempt added to your total.

Levels

Levels are a quick summary of the experience points you have received so far. As you collect more experience points your level will increase. The number of experience points needed to progress levels increases at each level, so it becomes harder and takes more effort to increase your level as you progress. You can compare your level and experience points with your friends as a way of seeing who is putting more effort into their learning and revision!

Stars

Stars are awarded for scoring well on quizzes. You will receive one star for taking a quiz, two stars for scoring 50% on a quiz and three stars for successfully mastering a quiz and scoring 80%. If you score 100% on a quiz, your central star will become larger (just to give you that little bit of extra motivation to score 100%).

You can see the total star count that you have received for each course in the course summary stats and the total star count you have received overall at the top of the app in your app summary stats. Your total star count will only increase if you increase the number of stars you receive for a quiz; if your best result for a quiz so far was two stars and you retake that quiz and receive three stars, then your total star count will only increase by one star. Your total star count will never go down and can only ever stay the same or increase; if you retake a quiz and nominally receive less stars than your previous best attempt at that quiz, your stars will not go down for that quiz and your total star count will not either.

When you score 80% on a quiz and are awarded three stars, you will enable the memory strength bar for that quiz.

When you score 80% on an exit quiz for a unit and are awarded three stars, you will also receive the crown for that unit and unlock the next unit in the course.

Crowns

Crowns are awarded for successfully completing units. The usual way to successfully complete a unit is to score 80% and receive three stars for the exit quiz for the unit.

Once you have received a crown for a unit you can never lose it. However, you should check the memory strength bar for the unit (which mirrors the memory strength bar for the exit quiz for that unit) regularly and retake the exit quiz when the memory strength bar reaches 50% and turns orange




How do memory strength bars work?

Memory strength bars are designed to help you push knowledge you have learned from short term memory into long term memory. Once you have achieved three stars for a quiz your memory strength bar for that quiz will appear. Over time the length of the memory strength bar will decrease and when the length of the bar reaches 50% the bar will turn from green to orange to let you know it is time to retake the quiz and refresh your memory.

Initially the length of the memory strength bar for a quiz will decrease quite quickly and you will need to retake the quiz quite often. However, each time you retake the quiz (and score well), the length of the memory strength bar will decrease at a slower rate than before. Eventually, will decrease very slowly as you will have pushed the knowledge into long term memory. Indeed, retaking the quiz around 5 to 7 times at the appropriate intervals should push the knowledge into long term memory.

Units also display a memory strength bar which simply mirrors the memory strength bar for the exit quiz for that unit. Moreover, the total aggregate memory strength for all exit quizzes in a course is shown at the top of each course and in the course summary card on your Dashboard. This makes it easy for you to quickly see which courses have units that need refreshing.

Memory strength bars are based on the science of spaced repetition and the forgetting curve. They provide a useful visual means to tell you when the optimal time is to refresh your memory.




How do I unlock units?

To unlock a unit you must have successfully completed the previous unit, to unlock the fourth and later units, you will have to purchase the course (the first three units are free).

To successfully complete a unit, you need to pass the exit quiz for that unit by answering 80% of the questions in the exit quiz correctly. When you do this, you will receive three stars for the exit quiz which will also grant you a crown for successfully completing the unit.




Can I access quizzes in units I have not unlocked yet?

Yes you can!

To quickly jump to a quiz in a unit you have not yet unlocked (and assuming you have paid for the course) go to your Dashboard and search for the quiz in the "Find Quiz" box. All quizzes from courses you have purchased can be started from here.

After you have taken the quiz the first time it will appear in your "My activities" list, so you can find it again more easily later.
