Some people study well in a group since they can get help from others in areas in which they are lacking. They may also gain valuable insight from others on what they have overlooked and which critical areas to focus on for the test. On the other hand, some people study well alone. They know what they have to study. A group can be distracting as they engage in off-topic conversation or try to do absolutely everything but study. You're the one who knows yourself the best, so determine what works best for you.
There are various methods you can use when studying. For example, when studying for a test, you can do different things, like reading through your textbook, reading through course notes, answering textbook questions, redoing past assignments, reviewing previous tests, researching online, talking with others, and more. You can also use memory-improving techniques like mnemonics, visualization, and association. Try a combination of different studying methods and track your results.
