Do I also need the Law & Business exam?
For a first license, almost certainly. CSLB requires the Law and Business exam from almost every applicant in addition to the trade exam, and you have 18 months from the day your application is accepted to pass both. Already licensed and adding C-29 to your license? Then you take only the trade exam. How the whole process works.
