Make sure yo have your full attention mode on during class, take detailed notes, study hard, review with friends, and try to study really hard a week or two before a test or quiz. Always get homework done FIRST when you get home from school and double check everything before doing something else, never skip an assignment or class, and review your lessons after a class or at the end of the day. Make sure you always know when something is due on a agenda or day planner, and keep track of important dates. Try and do extra credit if available, too. If you don't understand something ask the teacher, parent, or friend. If you are struggling bad in a subject get a tutor. One last thing: NEVER PROCRASINATE or put stuff off because you are to tired or want to do something else. Hope I helped and good luck! :)
A great thing to do is to simply work hard in each class until your first tests come up. Once you've taken your first tests, you can see where your teachers tend to take their test questions from and what kind of test they give. I say this because tests are worth the most.
your main focus behind getting all A's must be not to study like a jerk. study smartly. develop an interest in your subjects. enjoy them. ask as many questions as you can from your teachers. never mix work and play. and always find time to enjoy in between. best of luck :)
