Start by being nice to her. Help her with homework, hang out if she is ok with that, and maybe do some joint activity with her friends. Depending on either of your maturity, if you like one another's company, it will work. Invite her to a movie. Most 17 year old girls are typically more in tune with older guys who are also focused on graduation, college, SAT's/ACT's, driving, AP courses and where to apply to college. When you are one or two grades behind, it can be tough, but not impossible. Best wishes.
