StudyBlue Offers Millions of Flashcards for Popular Subjects
Internet / iOS / Android: Whether you are in school or a full-time student, using flashcards will help you remember the information you are learning. StudyBlue is a crowdsourced collection of these tutorials.
We mentioned StudyBlue before , but it has changed (for the better) since then. You can now register without going to a college connected to the app (although if your school is, you can add certain lessons you attend), and in addition to creating your own flashcards and testing on them, you can access the cards of others people on a variety of topics, from algebra to zoology.
There are decks for high school, high school, college, and general topics like business and technology.
The free version offers you recommended card sets for your interests, while the $ 7 / month paid version (billed annually) gives you full access to all 250+ million decks.
