Sadly, there's no RIGHT way. But that also means you can enjoy the quizzes in whichever way you feel 'right'.
Quizzes are arranged in basic topics with some subtopics. Questions are chosen to represent different areas of the topic. For instance a quiz on planet Mars will have questions on geology, atmospheric features and observations.
You can practice by doing the quizzes again. Most of the quizzes are difficult, so don't worry if you get a low score. Try again later after revising your astronomy knowledge.
