CONTRACTOR LICENSE PREP: PASS YOUR STATE GENERAL CONTRACTOR EXAM The general contractor license exam combines business and law, construction safety, project management, and building codes in one sitting. Most states have a first-attempt pass rate under 60 percent. Candidates who fail are typically weak in three areas: lien law deadlines, bid and markup math, and workers compensation calculation. This app is built around those three gaps with the professional calculators no other exam prep app offers. BID ESTIMATOR Every licensed contractor builds bids. Knowing bid math is tested on every contractor licensing exam. Enter material costs with waste factors, labor hours and rates, equipment costs, subcontractor amounts, overhead percentage, profit margin, and contingency. Get total bid, cost breakdown by category, markup vs margin analysis, and a formatted bid summary. Save and compare multiple scenarios. The difference between markup and margin alone has failed thousands of exam candidates. This tool teaches you both before exam day. LIEN DEADLINE CALCULATOR Mechanic lien law is one of the most heavily tested and most commonly failed topics on contractor exams. In real life, missing a deadline means permanently losing your right to file. Enter your project start date and state to get every critical deadline: preliminary notice (20 to 60 days depending on state and role), mechanic lien filing (60 to 120 days), lien release and waiver deadlines, and state-specific rules for subcontractors vs prime contractors. Covers all major states: California, Texas, Florida, New York, Illinois, Arizona, Georgia, North Carolina, and Washington. BOND AND WORKERS COMP CALCULATOR Licensing exams test bonding requirements and workers comp premiums. Candidates who cannot calculate a premium from payroll and a classification rate fail these questions consistently. Workers comp: premium equals payroll divided by 100 times classification rate, adjusted by EMR. License bond: required amounts by class, surety vs cash. General liability: per-occurrence vs aggregate limits. 1,000+ PRACTICE QUESTIONS BUSINESS AND LAW (35%): Mechanic lien law, contract law, business structures, workers comp coverage and penalties, bonding types, insurance requirements, employment law, dispute resolution. PROJECT MANAGEMENT (25%): Estimating and bidding, critical path and float, change orders, subcontractor management, project documentation, earned value basics. CONSTRUCTION SAFETY (20%): OSHA regulations, fall protection trigger heights, excavation soil classification and shoring, scaffolding, electrical safety, LOTO, hazard communication. BUILDING CODES AND TRADE KNOWLEDGE (20%): IBC and IRC fundamentals, permit and inspection sequence, plan reading, concrete and framing basics, energy codes. Every question includes a detailed explanation covering why the correct answer is right and why the wrong answers are wrong. FREE: 5 questions per day. Basic bid calculator. 3 lien states.
