If you really like science or mathematics and would like to study a STEM major in college, there are incredible summer programs to inspire and motivate you. The better summer programs offer intensive 4-8 week long experiences that require an application to be admitted as well as commitment to sciences or math. Why wait?
In fact: you can't afford to wait. If you want to earn a place at some of these competitive programs, and potentially earn financial aid or scholarships, you should start working now. The winter break is the best opportunity to prepare for upcoming deadlines in late winter and early spring.
