School is a complicated thing. You want to socialize and have fun, but also do well and give yourself the best change for a future. It's important to buckle down and earn good marks, but it can be easy to push your work to the background. Anyone can learn to do well and improve their scores to start doing their best. Scroll past the jump to learn to get better grades.

1, Create a positive attitude
You may ask "how does creating a good attitude supposed to boost up my mark?" Well, if you create a good attitude in studying and think positive things about studying, it's likely that you will start liking a subject that you were really not fond of before. You may also get marks for having a good attitude and for not disrupting a class.

2, Attend your classes regularly
If you attend classes daily instead of skipping them, you will be there to listen to all the lessons the teachers are teaching and won't miss important days. It's likely that you will remember or learn more if you are in class when the teacher is teaching than if you skipped class and then take notes later on.
3, Set goals for yourself
Set goals like 'get good marks in math, science etc' for yourself and then try your hardest to achieve those goals. If you fail once, don't give up, keep trying.
4,Do your homework daily
When you get homework, do it, don't leave it. If you're tempted to watch your favourite TV show instead of do homework, think about it this way: Is your favourite TV show going to help you get to a good university and possibly help you achieve the job of your dreams? If the answer is yes, then by all means watch the show. Homework is important because it gives you practice on the subject that you are learning. Always do your homework.
5,Ask for help when you need it
If you have a question on something, ask for help, don't just leave it behind. You can ask anybody who has knowledge on the subject that you need help with like your parents, teacher, brother or sister. It will most definitely help you in tests and quizzes.

7, Always review
After school, review what you learned that day.

8, Develop tests for yourself
This will really help and increase your confidence when taking exams if you're familiar with the typical exam format, common errors to avoid, and know how the concepts in a subject area usually tested.
So i think if you do 8 steps above, you will get good marks at school !!
