Revising for a Specialist test
CITB’s revision book and app are titled for operatives and specialists, though CITB lists the book as covering sections A to E only. The app includes a realistic test simulation, and CITB’s Specialist page links a demo test that previews the question styles but isn’t scored. Our 20 practice questions cover the core areas every Specialist test includes. The pass mark is the same as the other versions.
