Built by a California contractor
CXP is a study app for California CSLB exams, with practice questions, clear explanations, and timed mock exams in English and Spanish.
Why I built CXP
Erik · CXP founder · Licensed California contractor
I took the CSLB exam myself. I built CXP to help other contractors understand what they know, find what needs work, and practice around a busy workday.
My background includes 15 years in commercial and residential contracting in California, followed by 11 years in public education and edtech.
Support comes directly to me
I personally read the support emails. If a question is unclear or something isn’t working, tell me so I can look into it.
