C-20 Fast Track Pass Kit: 2026–2027 Edition
Short description
Everything needed to study for the California C-20 HVAC trade exam and the Law & Business exam on one eight-week schedule. Six lessons, 225 practice questions with worked answer explanations, a printable tracker, and a formula sheet. Independent study material.
What's included
- The full eight-week self-study workbook: six lessons mapped week by week, from air systems and licensing basics through safety, hazardous materials, and Law & Business
- 225 practice questions with full answer explanations: 100 C-20 trade, 75 Law & Business, 50 mixed review
- Domain index so you can drill the weak areas instead of the whole bank
- The 8-Week Study Tracker & Error Log: printable, tracks per-domain misses and why each wrong answer looked right
- The Quick-Reference Formula Sheet: every calculation convention used in the bank on one page
How it works
Eight weeks, six lessons, one drill schedule. Each week has a study map and a question-ID range so you always know exactly what to work next. Wrong answers go in the error log. The log is what you review before the exam, not the whole bank.
The schedule is a plan, not a promise. Miss a week, restart the week.
