Summarize this article in one sentence.
When your teacher says a test is coming up, avoid cramming the night before. Plan to study for about 60 minutes each day to brush up for the test. Re-read the book chapters you’ll be tested on and look over your relevant in-class notes to see what mistakes to avoid. If you have time, you could even test yourself with flash cards or form an impromptu study group with your friends. If you find that you’ve forgotten some of the math lessons or are still struggling with a tricky concept, ask for help! The teacher will appreciate your earnestness and won’t mind answering your questions. Study groups are a great way to prepare for a test and a useful method for improving your math abilities in general. They let you and your peers ask each other questions about topics that confuse you and review material that’s going to appear on an upcoming test or exam. Try studying with flash cards, or working difficult problems together.  Keep focused during group study time! If it turns into a social hour, your math skills won’t get any stronger. If people start joking around or lose focus, say something like, “Hey guys, I’m glad we’re having a good time, but let’s keep focused on the math we came here to study.” Many people are anxious or nervous during math tests. Feeling this way can diminish your performance, unfortunately, and can lower your math grade. So, take a deep breath before you go into the classroom to stay calm. If you feel yourself tensing up during the test, stand up, stretch your legs, and take a 2–3 minute break to calm down. Also make sure you get a good night’s sleep and eat a full, healthy meal before going in for a math test.
Plan to study for 3–4 days in advance of an upcoming text or exam. Study in a group of peers to help each other improve at math. Stay calm and focused during tests to do well on them.
