High school coding contests are more than producing lines of code. They're an opportunity to bring your ideas to life as actual projects such as making an app for mental health support, coding an indie game from scratch, or graphing NASA's data. These contests are challenging and you need to think outside the box and be creative with your implementation. Along the way, you'll improve your logic, STEM abilities and most importantly learn to work in teams. And, doing these competitions is a plus on college applications, demonstrating that you're proactive and can combine skills from multiple disciplines to create something with substance.
