Deciding between EC's

When I entered my ECs in Collegevine to see my chances of getting into certain colleges I was surprised to learn tutoring itself didn’t add much value. If you started a chapter at your school and could show a large number of participants that would be a boost. Winning a competition or developing an app used by a high number of people would be a bigger boost. For ECs it’s about the impact not the quantity. National impact is better than State impact which is better than school impact, etc.

Perhaps you should take on the tutoring. If any part of you didn't really like that answer while reading that, then maybe deep down you knew that you wanted that extra hour to work on the competition. Otherwise, I say go for both! From my experience with computer science classes, which I've learned I enjoy, I think I'd personally want an extra hour to work on building an app or solving problems. If you're still stuck, you can also list out pros and cons. I hope this helps and I wish you all the best with your app!

You should go for both, work on the web development for your app to enter the competition, and tutor. These would be great items to list on your application etc when you start applying for colleges. Showing that you have a passion for ECs you are in from the start of your high school career, allows the colleges to know you are committed to what you do. Tutoring also helps you further understand the topics you teach. Besides, you are only investing an hour out of your schedule to tutor. Best of luck at your competition!
