The main objective of going to school is to learn and study. Do not waste this valuable time in any other things.
Don’t procrastinate in doing your assignments. Once you know they have been assigned, concentrate in completing them, even before the due date.
Be an active collaborator in the Q&A in your classroom. Participate in all your academic activities and ask questions and share your knowledge and experience with the group.
Arrive at least 5-10 minutes before the beginning of any school activity.
There will be always groups of student with the same interest that you have, be part of those groups. Make friends and participate in extra-curricular activities to enlarge and develop your support group.
