Learn the Code. Mark the Book.

Stop flipping. Start finding.
The Exam Timer is Running.

You know the answer is in the book. Somewhere. The clock is running, the pages blur together, and you're second-guessing every number. This free mini course shows you how to mark your code book so the answer jumps out at you before the clock runs out.

Sound familiar?

  • You pass the right section going left, then going right, and then you find it hiding in a corner.
  • You find a number that looks right, then miss the footnote or exception that changes it.
  • Your highlighting has turned into one blurry mess.
  • You're tired and flustered, and simple conversions like feet to inches start costing you time.

What you'll walk away with

  • A clean, repeatable color system: light blue to navigate, pink for landmines and exceptions, yellow for key concepts and look-alike tables, plus orange and green.
  • Blue-pen habits that take the work out of exam day: underlining measurements, converting feet and inches, rewriting spelled-out numbers as digits, writing in page references, and drawing symbols for slopes, percents, spheres vs. diameters, and < > ≤ ≥.
  • The confidence of a book that's built for you, so you scan for pictures instead of rereading code.
  • A system you can reuse on any open-book code exam.

On the ICC B1 exam you get 60 questions in 2 hours, which is 2 minutes per question. Every second you save finding an answer is time you can spend getting it right.
