examCode, jurisdiction, administrator, codeEditions, officialBulletinUrl, eligibilitySummary, eligibilityUrl, format: Not verified — The publisher source establishes the code only. No official board or exam bulletin was verified for this bank; no stateRows are supplied.

Catalog timing and practice target are custom practice settings, not official exam requirements.

Question counts and topics describe the local bank; publisher research is not a fresh question-by-question accuracy audit.

No state adoption or exam-reference rows are asserted.

The local bank includes 191 IMC 2021 items and nine IFGC 2021 combustion-air items; this is not a pure IMC-only filter.

Verification sources and scope

Verified: ICC (International Code Council) publishes IMC 2021. The publisher source identifies the code, not a state licensing credential. Confirmed only within the stated source scope; product scope is an editorial boundary, not an official alignment claim.

Verified: General-practice product scope; topic coverage is the local JSON inventory, not a publisher endorsement or audited exam blueprint. Publisher scope cross-checked with the local bank and its editorial notes; exclusions describe what CodeReady does not provide.

Not verified: No specific licensing exam, state adoption, administrator, eligibility, official tested edition, bulletin, or official format has been verified for this product. The publisher source establishes the code only. No official board or exam bulletin was verified for this bank; no stateRows are supplied.

Preparing, qualifying, passing, receiving

  1. Preparing: CodeReady provides independent study materials.
  2. Qualifying: Meet the issuer’s eligibility, application, experience, and training requirements separately.
  3. Passing: Complete the required official assessments; a practice percentage is not an official result. OSHA Outreach requires authorized training, not a CodeReady test.
  4. Receiving: Only the responsible issuer can award the credential or card after its requirements are met. Buying or completing this bank does not confer one.
State guides and credential resources

No state adoption or state-exam alignment is asserted here. Check the responsible licensing authority’s current bulletin separately.

What you get / what you don’t

What you get: Access to this practice bank, cited explanations, flashcards, browser-local progress, and practice tests. Tests use eligible reviewed items only; test sizes can be smaller than the bank.

What you don’t: A license, certification, OSHA card, exam voucher, authorized training hours, practical assessment, hands-on lab, or official performance-based question simulation. No guaranteed exam result or claim of exhaustive objective coverage.

$39 buys this bank for the operating life of CodeReady. All-access is $79 lifetime or $19/month while subscribed.

Retake-access extension: monthly subscribers may request one free month of continued access after a documented exam attempt within 60 days. Single-bank and lifetime buyers already retain access; this is not an added benefit for them. Terms.

TAKE IT FOR A TEST DRIVE

Three questions. No sign-up.

01 / Administration and definitions

When a general IMC requirement conflicts with a provision written specifically for the installation being reviewed, which governs?

  1. The general provision
  2. The specific provision
  3. Whichever costs less
  4. Whichever was printed first
Show answer & explanation

The specific provision

The specific requirement takes precedence over a general one. This differs from choosing among conflicting requirements for the same specific case.

IMC 2021 §102.1

02 / Administration and definitions

Who is responsible under the IMC for maintaining a building's mechanical systems?

  1. Only the equipment manufacturer
  2. The owner or the owner's authorized agent
  3. Only the code official
  4. Only the original installer
Show answer & explanation

The owner or the owner's authorized agent

Maintenance responsibility rests with the owner or authorized agent, even though inspections and service may be performed by others.

IMC 2021 §102.3

03 / Administration and definitions

An installation uses a term absent from the IMC but defined in the IPC. How is that term interpreted?

  1. Treat the term as a product brand
  2. Ignore the term because it is absent from the IMC
  3. Use the meaning assigned in the referenced companion code
  4. Use only the contractor's preferred definition
Show answer & explanation

Use the meaning assigned in the referenced companion code

Section 201.3 directs readers to definitions in the specified companion codes when the IMC does not define a term.
