Practice benchmark only: the WPI standardized Wastewater Collection Class I exam carries 100 scored questions plus up to 10 unscored pretest questions, and passing is 70% in the states that publish a cut score. This practice exam flags 70% as a PRACTICE BENCHMARK ONLY, set to mirror that published standard; this 100-question draw runs on a 180-minute practice clock. It is a study signal, not a WPI result.
