Waiting time before being able to reapply for university?

I think waiting time for university is too long overall. My sims usually already has a career going and a family of their own cooking before anything happens with the application so most of the time I just let them skip it, as it becomes meaningless and too late. Application should be done already in their teens so they can start immeditately as they turn young adults and it should take one day maximum from application to get it approved or not.
