OOPS! Grad School Actives???

[CASIGKAP]

Sorry. I posted this in another thread when I should have posted here. I go to a Cal State school.
My question is can you remain an active if you go to grad school or do you have to go alum?

Also, if you're in a credential program can you remain an active or go alum???

Thanks! I am curious b/c I have one year to go before I graduate but plan on either going to a credential program or if I get accepted, plan on getting my Masters here at my school. I would like to remain an active but will go alum if necessary.

P.S. I am very effective with time management so remaining up to date with all my activities, school, and work would not be a big problem.
