What you do in the summers matters to all colleges. Try to sign up for a community college math or science class
or go away to a college experience, such as Hampshire Math.
Take your SAT subject exams in Math 2 and your strongest science: biology, chemistry or Physics.
Do you have FIRST robotics available? Try that too to learn more about electrical engineering.
