Activities Section: Which ones to choose, should I combine them?

Okay, So I have around 20 extra curriculars I participated in over my 4 years in high school. I need to cut the list and I wanted to know if I should combine some activities to make room for others.

I was part of a robotics team freshman year, we won an award at regionals and placed 10th at states, but I didn’t continue it through the rest of high school beccause I strongly disliked my team members for personal reasons. Should I include the robotics team on my app?

I started a chess tutoring business with some of my friends
I volunteered at chess summer camps
I am vice pres of chess club- we organized a lot of school chess stuff and travel to competitions
I have been playing chess individually since I was very young and am highly rated with national awards.

Should all of these activities be seperate or should I combine some?

I did 2 different research opportunities at different universities on different summeres.

Can I combine the research opportunities or should they be seperate?

Science Olympiad- lots of regional awards from 9th to 11th grade but no state/nats
Should I include it?

Math Club- President and founder- we prepped for local math competitions and amc
We didn’t really do very much in this club. Should I include it?

I won a random physics competition- but I have no other physics awards, can I put this in additional info?
I’m also a black belt in taekwondo
I am in comp sci club and won a couple of programming competitions in 11th grade and will do it in 12th.
For half a year in 11th grade I did a tutoring program for 3rd graders.
I ran a physics club in 11th grade at my school where we prepped for competitions.
I participated in a science tutoring program for elementary school kids in 11th and will do it in 12th.

I am in a couple of cultural and dance clubs. These are kind of a low commitment thing that I do for fun. However, I feel like it’s important to include them as otherwise it seems that I am in only “academic” type clubs, and it doesn’t show the facet of my personality that cares about the community. To do so, however, I would have to get rid of “bigger” extracurriculars, like president of math club or something.

Ugh! I can’t choose what to include! What do I put in the additional info section? What about the honors section? Can I squeeze things, so that I get everything I feel is essential?

Is it possible to group them according to their categories?

My two cents…
Combine chess but start with your stronger leadership type roles like names of Nat’l awards, VP, business owner, etc.
Research should probably be separated since they were at 2 different places
Can you combine include robotic w/ physics & comp sci clubs?

Science Olympiad keep alone since it shows commitment for 3 yrs

Choose the ones that speak best to your leadership abilities and your passions.
