Take the CA DMV Permit knowledge test(s). You have to get at least 38 questions right out of 46. You get 3 chances to take the test, but if you fail a test you have to wait 7 days (not including the day the test was failed) before taking the test again. If you fail the test all 3 times, you have to start over by filling out a new application and paying the fee again. So make sure you study!
