So is there like colleges or schools in sindome so that if my character i wants to be a doctor he can receive an education to do so. Also so i prove to hospitals and such that i'm experienced on a resume.
You're not going to RP going to college and doing homework (this isn't a real life sim)
but, your character could certainly study for whatever they want when you're logged off. No ones character just sleeps for hours and days when you're not playing. Imagine that your character works on skills, stats, studies, exercises, etc when you're logged off. Whatever you want to improve.
