ECs for a Comp Sci major?

TL;DR at bottom

Hi. So I’ve been torn between majoring in comp sci or biology, and my activities and classes kind of reflect this indecision. For example, I took a computer programming class in freshman year, however I didn’t go on to take the advance programming class and took the science research class instead. Then after I did some cancer research at my local university, I realized how boring working in a lab is and how frustrating it is repeating the same lengthy experiment if you messed up one little thing. So now I decided to self study for AP Comp Sci A (since it’s too late to take the class) and AP Stats (I made this decision this past spring, so it wasn’t too late).

What are some ECs that will compliment a comp sci major?

My current clubs are:
Math League
Math Honor Society (Former VP and P)
Science Olympiad (VP)
Model UN
National Honor Society (Secretary)

I’ve been hesitant about doing robotics this year, since: 1, I am the Science Olympiad Vice President, which already requires a lot of time. 2, My school’s robotics team is only regional level, they haven’t gone to Nationals or anything in the years I’ve been in highschool (going into my junior year). 3, the most I can participate in the Robotics club for the remaining years of highschool is 2 years, I feel like this doesn’t carry the same weight as a comp sci major who does it for 4 years.

TL;DR
Good comp sci ECs and/or classes besides robotics?

You don’t have comp sci ECs to be a comp sci major. I would take another programming class to see if you like it.
Also for biology research, realize that you have the lowest of the low tasks.

It seems like you’re doing plenty right now. If you’re hesitant about robotics, that probably means you simply wouldn’t be as committed. Considering you would be just starting robotics, while it seems like you’ve spent far more time on the rest of your ECs, that would make robotics look like just resume padding, especially since your other ECs are pretty meaningful.
