The useful thing about quiz scores is that they are hard to improve by any method that does not also make you better at the underlying skill.
Review what you got wrong, not what you got right
The most common mistake is finishing a quiz, noting the score and moving on. The wrong answers are the entire value. Going back over them is what converts a quiz from entertainment into revision.
Use the courses
Courses are included in membership at every tier, including Free, and they cover the same ground the quizzes test. A member scoring poorly in an area and not taking the course for it is skipping the obvious step.
Space it out
Twenty questions a day across a week beats a hundred and forty in one sitting. Not because it is more pleasant — because spacing is how things stay learned rather than being briefly familiar.
Stay in one area until it moves
Jumping between skill areas produces a set of scores that are all mediocre. Working one area until the score climbs is slower to feel good and considerably more useful, particularly if that area is the one you intend to be assessed in.
Read the question properly
A meaningful share of wrong answers on any quiz are not knowledge failures. They are questions answered too quickly. Slowing down is free and usually worth several points.
Use quizzes to decide about the exam
Skills exams cost $5 an attempt with a seven-day cooling-off between them, and pass rates are published per badge so you can see the odds before you pay. Consistent quiz scores in an area are the cheapest evidence you have about whether that $5 is worth spending now or after more preparation.
What will not work
Guessing quickly to accumulate diamonds. Correct answers earn, so speed without accuracy earns nothing — and it teaches you nothing about whether you are ready.
