Sometimes, studying for exams can seem boring or lonely, but it doesn't have to be! There’s no reason why learners shouldn’t occasionally benefit from joining forces with a friend or friends and revising with them.
After all, if there are two or more of you, you can benefit from each other’s strengths while supporting each other in the areas where you need to improve.
For example, you may find that you’ve each taken away something different after attending the same lessons, so start by comparing the notes you took.
Additionally, if you have differing views on an issue you’re learning about, that can help bring a subject alive. You’ll certainly learn to argue your case! Equally, if you have to explain something to someone else, you’ll deepen your own understanding of the topic.
That said, you need to be sure you and your study buddy or buddies are genuinely benefiting from your joint sessions. You should have specific aims or goals each time you get together, rather than a vague notion of "meeting up to study or revise". Are you supporting each other to pass a particular exam, complete a specific project or work through the basic elements of a subject?
