Does this cover IPC or UPC?

Both. Every question is tagged with the code family it applies to (IPC, UPC, or "both" for shared concepts).

How do I know which code my state uses?

See the state-specific landing pages below — each one names the adopted code, edition year, and any major amendments. IPC and UPC adoption is roughly split coast-to-coast.

Is this the real journeyman plumber test?

No — the licensure exam is administered by your state board (often via PSI / Prov / Pearson VUE). This is paraphrased study practice with full explanations.

No. The warm-up question set is ungated and the 25-question study PDF downloads free. Only the full-bank PDF is gated by a newsletter signup.
