Whether you're new to Quizlet or not, the quickest way to get started with studying any topic is to search for sets made by other users. To do that, you simply need to tap the magnifying glass icon.
Then, type the subject you're looking to study into the text box at the top of the screen. Once you've entered a topic, the results will auto-populate below.
If you don't find what you're looking for, you can tap the x icon to the right of the search bar and enter another search query. To get started with studying, tap on a set title and select the mode you'd like to use for review.
