HOW do I improve my schoolwork?

Here's HOW:

H - Honesty. Ask yourself: Am I putting forth my best effort? Am I prepared for tests and projects?

O - Open-mindedness. Ask yourself: Do I have a good attitude? Am I judging the value of the class/subject matter fairly?

W - Willingness. Ask yourself: Am I willing to work hard? Am I trying my hardest to get along with others?
