Take home examination - CA in Anything about the PE Exam Posted November 26, 2010 · Report reply California has a take home PE exam or is it a supplement exam to PE like seismic or survey? It's actually considered a 4th exam. It's a test you take at home and mail in with your application. It's based on the Professional Engineer's Act and the Board Rules. There are 25 questions and you must get at least 70% correct. If you don't get 70% the CA State Board will still process your application and allow you to sit for the PE Exam, but you will need to pass the take-home test before you get your PE Registration. Link, if interested. It's actually pretty time consuming and I felt a bit iffy on a good 4-5 of them. It's kind of a bummer that the state never tells you that you passed (at least I never heard anything). I have to just assume I passed or else I would have been told to re-take the take-home test. ?
