C-20 FAST TRACK PASS KIT
C-20 Fast Track Pass Kit — 2026–2027 Edition.
Six lessons, 225 practice questions with worked explanations, a printable tracker and a formula sheet, all mapped to one eight-week schedule. Eight weeks. And a lot of people won't hit that.
The schedule is a plan, not a promise. Miss a week, restart the week.

THE HONEST VERSION
Eight weeks. And a lot of people won't hit that.
The workbook is built as an eight-week study sequence: read the lesson, work the practice without the key, log the mistakes, retry them two days later, then sit the mixed review closed-book.
Many students take longer than eight weeks, and some take much longer. That's expected — this is a real licensing exam and the schedule is a plan, not a promise. Miss a week, restart the week. The workbook doesn't expire and there's no subscription.
No hype. A plan, a question set, and an honest answer key.
