I just got finished with my motorcycle courses approved by the DMV but what do I do now?

So I am 17 years old and just finished the classes so the next step is taking teh DMV written test for motorcycles right? After that do i have to wait 6 months in order to drive on the freeway? Or can I drive on the freeway once I get the license because the bike shops are in other cities? I live in California and have already had by drivers license for a car for 5 months.
