How to add your school in GAS app?

so how to add your school in gas app so what they say here in the support center that uh our school list should contain all U.S high schools but sometimes you miss one if your school is not appearing when searching please email at casab.co and include the full name of your school city and state and the abbreviation so all of that should be available um yeah for that so that's basically the idea yeah usually they have a lot of these schools available but just not all schools have members as you can see a lot of schools don't have members so that's the issue
