How should I rank my activities?

I am applying to multiple ivies as well as duke and Stanford for computer science (and some safeties as well). I am unsure of how to rank my activities by importance and would appreciate any feedback! Activities listed below in no particular order:
NHS president senior year(member junior and senior year)
240 hours volunteering at a combat support hospital
200 hours church choir volunteer
Varsity tennis captain junior/senior year(varsity since freshman)
MUN Officer Senior year (member since freshman)
All-county concert master (sophomore year, played all-county since freshman year)
all-state violinist (sophomore to senior year)

Thank you!

The most interesting one IMO is the combat support hospital. How does it relate to your intended major, if you have one?

Put the activities in order of how meaningful they are to you. Admissions officers will read it all.

And as a side note it sounds like you could use some match schools. – from your post you seem to have only schools that are reaches for everyone and safety schools on your list.

Sort by the importance to you.
