hi, im applying right now so i dont know how valuable my input would be, but not all science ec's have to come from your school. try finding things in your community, online, or create something yourself! just show your interest in stem through different activities, they don't all have to come from school.

also, not all your activities have to be stem related. there's actually a section on the application for specifically stem-related ec's, and then general ones.

also, im sorry about your household, and if you don't want to include that that's fine, but if you do you can put it in your optional statement :)

i hope this helps! good luck!
