ICC M2 study plan

Map every chapter of the code book to one of the five exam domains and label each chapter with its domain number

Define the scope and administration terms in your own words and write a one-line plain-language gloss for each

List the permit, inspection, and approval sequence in order and annotate where each step can fail

Build a personal index of the sections you will need to look up most often during the open-book exam

Trace the clearance-to-combustibles requirements for each appliance category and record the numbers in a comparison table

Explain how appliance category and venting method constrain where an appliance may be installed

Work through ten practice scenarios on appliance installation and write the governing section for each answer

Draft a checklist a field inspector would use to verify a furnace and water heater installation

Compare the duct construction and sealing requirements that apply to different pressure classes

Sketch three duct layouts and mark where support, sealing, and clearance requirements apply

Summarize the ventilation rate and outdoor air requirements and show one worked calculation

Identify the five most commonly confused duct and ventilation provisions and write a rule to distinguish each pair

Diagram the combustion air methods and label the opening sizes and ratios for each

Explain how Category I through IV appliances differ and which venting rules follow from each

Trace a chimney sizing and height problem from input data to final answer without notes

List the ten most testable combustion air and venting numbers and memorize them

Outline the refrigerant classification and safety group system and give one example of each class

Describe the hydronic piping requirements for expansion, relief, and isolation and where each is required

Summarize fuel piping sizing, materials, and testing requirements in a single reference sheet

Work through eight practice problems spanning refrigerant, hydronic, and fuel piping

Re-solve the missed questions from weeks 2 and 4 and write why each original answer was wrong

Build a decision tree that starts from appliance category and ends at the correct venting method

Practice locating ten random provisions in the code book within two minutes each

Teach one venting concept aloud to an imagined apprentice and record where your explanation breaks down

Re-solve the missed questions from weeks 3 and 5 and note the section that governs each

Combine duct, ventilation, refrigerant, and piping rules into a single cross-domain quick-reference card

Complete a timed 40-question mixed set covering domains 3 and 5 and score it

Identify your two weakest subtopics and write a targeted drill for each

Take two full-length timed practice exams under exam conditions and score both

Review every missed question and tag it to a domain and a specific code section

Re-drill the tagged weak sections until you can answer without hesitation

Finalize your exam-day index and confirm your lookup routine works under time pressure
