Whether you plan to study computer science as a major or not, knowing some computer science will be a valuable tool in ANY career path that you choose! Computer science is about learning how to THINK. You'll learn to think differently than in any other class you've taken, and you'll almost definitely have fun along the way!
Computer science takes many forms and impacts our lives in so many ways. Why not try and learn something you've never done before?
There is really one key skill that matters in CS. Persistence. If you are willing to work at learning, you'll succeed!
The need for women in computer science is huge. Girls can be some of the best programmers out there, so give it a shot!
