California contractors who passed

Thank you Peerless. The pictures and charts made the hard parts easier to learn, and next month I am opening my own company.

Rosa San Bernardino, CA  · General Building (B)

I did not pass my first try, so I bought the study guide and read it every night after work. The drawings helped me more than the words did, and the second time I passed.

Marco Hesperia, CA  · General Building (B)
