CSLB Class B General Building — Trade Exam Study Guide (2026)

The CSLB Class B General Building TRADE exam (the craft half, distinct from Law & Business) — plans & estimating, framing & structural, core trades, finish trades, and Cal/OSHA safety. 58 worked examples with the arithmetic shown, 130 original practice questions, and every chapter closing on its own cited Sources list. Written to the 2025 California Building Standards Code effective 2026-01-01, which renumbered much of CRC Chapter 3 — guards R312 became R321, stairs R311.7 became R318.7 — so material written to the 2022 code cites sections that no longer exist. Every figure that moves by code cycle is flagged verify-current. AI-assisted study aid. PDF + EPUB.

CSLB Law & Business — Cram Sheet (2026)

A printable cram packet for the California CSLB Law & Business exam. Every rule in it is free to read on PrepPass — what this buys is the arrangement: every day-count, dollar figure and percentage pulled out of its chapter and grouped by value, so the numbers the exam confuses sit side by side; a RECALL twin of every sheet with the figures blanked, so you write each one instead of re-reading it; a concept self-test; four routes through the same pages for 14 days, 7 days, 3 days or tonight; and a fold-out exam-morning card. US Letter, print double-sided. California law changes — every page carries the date its figures were checked.
