Agree, the only kids earning a good amount of money when college is in session are very astute computer sorts. This isn’t about some come and go tutoring. If you get an off campus job, you have to get there, compete with locals for the work, work on their schedule (regardless of say, classes or an exam scheduled,) and it takes from study time.
These are all examples of what you have yet to learn about and process, before jumping ahead to envision yourself at one college. These assumpions lead to “pipe dreams,” not informed knowledge.
It’ s crazy to think we’re spending this much time on a case where only 9th grade is done. Ordinarily, we say, drop back, see how it goes, then ask questions when more detail is available.
You’re rushing this-- without proper background, first.
