free practice questions are here. There were another 10
free practice questions in the now-old 2007 California BBS
Candidate Handbook. Compared to the prep-course questions I've
seen, these were pretty much gimmes. Here's hoping they're more
like the actual exam.
Also in the handbook (current version linked here
exhaustive list of everything you're supposed to know for the exam.
The full list lasts pages. Treat it as a checklist, if you like.
Not advised. What you need to know for the social work licensing
exam, you mostly already know. You know if from school, you
know it from internships, you know it from work, you know it from
common sense. What's needed to pass the exam is sorting
by-the-book knowledge from real-world-get-it-done knowledge, and
applying the by-the-book to exam questions. The other
stuff? Save it for the real world.
