The Best Free Study Guides in 2021

August 26, 2021

When you think of the internet, the first thing that comes to your mind probably isn’t studying. The internet is a fun, cool, and wild place full of memes, cat pictures, and videos, and virtually conversing with your friends. When the internet was first introduced, many parents didn’t like it or agreed with it because they thought it offered nothing good to their children’s lives and only made them procrastinate. But now, it’s clear that this isn’t necessarily the case.

Thanks to the internet and other technological advancements, students can now easily access thousands of websites that were specifically made for learning or helping them with their schoolwork. There’s a wide range of study guides out there, and we’ve made a list of the best ones that don’t require you to spend a single dime.

GoConqr

The first on our list is GoConqr, and it’s a fantastic website ideal for visual learners. What makes GoConqr different from the other study guides is that it offers mind maps, a web of useful information that easily and conveniently breaks down major topics into smaller, bite-sized pieces, making them easier to digest and understand. You can create your very own mind map on the site for whatever you’re studying, and it can help you see how different concepts and ideas are connected.

Breaking things down into smaller topics or concepts helps with memorization too, rather than trying to remember huge chunks of information. Other than the mind map, GoConqr also has other study tools available, like self-created quizzes, flashcards, a study planner, a platform for taking down notes, and more. It’s available on more than just one platform, which means you can still use it on your phone or tablet when you’re busy and on the go.

Quizlet

If you’re not able to find a specific study guide for the subject or topic you’re studying, Quizlet can help you out significantly. With this app, you can provide the information while the site offers the study tools you need. You can freely create what you call “sets” in any subject you want. After that, the Quizlet will use the information you entered in the set to generate quizzes, matching games, auditory tools, flashcards, and practice tests. You can even study whenever and wherever you want—even offline!—as Quizlet has a free learning app you can download onto your smartphone.

There are two different games you can play on Quizlet that were developed to help you study—but in a fun way. These games, entitled Scatter and Space Race, ensure that you’re having fun while studying at the same time. In Scatter, you have to drag information or definitions to their respective counterparts as quickly as possible. The goal is to clear the screen as fast as you can.

Space Race, on the other hand, has definitions scrolling through the screen and you’ll need to type in the correct answer before it reached the end of the screen. This section of Quizlet also has leaderboards and high scores, so you can even motivate yourself this way by trying to be the best.

StudyBlue

If you’re the type of learner who likes collaborating with others, then you should give StudyBlue a try. This site connects you with other students based on subjects and whether you have the same learning goals. Once connected, you’ll be able to share and access study guides, flashcards, and a lot more. You can even connect with other students based on specific subjects or classes. This makes it extremely easy to collaborate and communicate with one another, especially if you have to work on a project together.

Other than that, StudyBlue offers a storage space where you can keep your note, class-based study guides, a wide-ranging content library, several study modes, and more. Just like the others, StudyBlue is perfect when you’re on the go, as you can download its mobile app to your phone.

StudyStack

Studying via flashcards is one of the best and most effective ways of studying, which is why we’re adding StudyStack to this list. StudyStack lets you create and customize flashcards to fit your needs, but you can also use ready-made sets other users have created. After flipping a card, you can pick whether you got the answer right or wrong. If you choose wrong, the flashcard will return to the pile and repeat until you get the answer right. As you can see, it’s a fantastic study tool for memorization.

StudyStack offers more than just flashcards, though. This site makes an effort to make studying and learning fun by using games to keep you engaged. For instance, you can play unscramble, matching games, hangman, and more using the information you’ve entered.

Hippocampus

Hippocampus is another fantastic website for visual learners. The site offers a vast collection of multimedia content and information on various subjects—from religion to economics, and more. Hippocampus is completely free of charge, and accessing the site allows you to view thousands of videos on all the different subject areas available.

Tinycards

If you want a way to easily organize and keep track of all your flashcards while still making it accessible for whenever you have a moment to study, Tinycards may be an app for you. Tinycards is by the famous language-learning app Duolingo, so you know for sure that it’s effective and worth your time. Tinycards has a wide collection of flashcards you can learn from, whether you’re studying animals in Antarctica or Greek philosophers.

Naturally, you’ll also find a plethora of flashcards that focus on learning different languages too, since this is by Duolingo. If you’re unable to find a specific set of flashcards for your needs, you can create your very own deck—and you can even share it with others.

Khan Academy

Khan Academy is a fantastic free resource that allows you to keep learning and studying even when you’re outside of class.
