What is the most important thing to know for the MHIC exam?

Work it through

You're the contractor. Pick what you'd do, then see how each choice plays out.

1. AKnow the contract requirements inside and out — 75% of the exam is Home Improvement Law, and almost every scenario comes back to proper contracts, licensing, and consumer protection
   Key insight

   41 of 55 questions (75%) are Home Improvement Law. The exam is open book — you can bring the NASCLA guide. So the key isn't memorization, it's understanding how the law applies in real situations. Know: contract requirements (§8-501), contractor duties (COMAR 09.08.01.08), advertising rules (.09), door-to-door sales (cancellation rights), subcontractor payment (.12), and the Guaranty Fund (.20). If you understand WHY these rules exist, the right answer becomes obvious.

2. BFocus on memorizing building codes — that's the technical stuff that trips people up
   Not the best advice

   Building codes matter, but they're a small portion of the exam. Home Improvement Law is 75% of the test. Also, the exam is open book — you can reference codes. What you can't look up easily is how to APPLY the law to scenarios. A contractor who knows every IRC section number but doesn't understand when a contract is required will still fail.

3. CDon't overthink it — it's open book, so just bring the guide and look everything up
   Overconfident

   The exam is 55 questions in 2 hours. That's about 2 minutes per question. If you're looking up every answer from scratch, you'll run out of time. The open book is a safety net, not a substitute for understanding. You need to know WHERE to find answers quickly, which means you need to understand the structure of the law. Tab your reference materials and practice with scenarios — exactly what this simulator teaches.
