Full-length timed mock exams. No account, no subscription, and no signal required. WHAT IS INCLUDED - 1000 practice questions, each with a written explanation and a topic reference - Core exam preparation: 50 questions, 90 minutes, weighted exactly as the certifying body publishes it - Basic Electricity 26%, Safety 18%, Temperature and Humidity 14%, Achieving Desired Conditions 14%, Tools 10%, Using Basic Science 10%, Basic Construction 8% - Three service specialty tracks - Air Conditioning, Air-to-Air Heat Pump, and Gas Heating - at 100 questions and 150 minutes each - 21 study lessons, one per exam domain, so a weak area on your stats maps to exactly one lesson - 24 field formulas, an R-410A and R-22 pressure/temperature chart, and 47 glossary terms - Spaced review: questions you miss come back on a schedule instead of disappearing - A blueprint-weighted readiness score showing where you stand against the 70% pass line BUILT THE WAY THE EXAM IS BUILT Most prep apps shuffle a pile of questions and hand you twenty. CoreForge draws each domain's published share for every practice set and every mock exam, so a weak 26% domain shows up in your score the way it will show up on exam day. Answer options are ordered fresh each time, so a repeat sitting is never memorisable by position. WORKS WHERE YOU WORK Completely offline. Nothing to sign into in a mechanical room, an attic, or a crawlspace. SOURCES AND STANDARDS CoreForge is an independent study aid published by TapForge Studios.
