Is this a good resume ? How can I make it better?

Looks good. To stregthen you resume, I would add information about volunteer work you have done, and ways you have helped your community. Also, mention high school sports, clubs, or any other activities that you take part in outside of school. Depending of what this is for, you should include GPA and other information that gives them an academic perspective of you. Overall, the layout is organized and well structured.
