Free utility test practice demos

A short taster of every section in the EEI batteries US utilities use — CAST, CAST-R, POSS and MASS. Each demo takes a few minutes and ends with your score. All items are original practice written from published descriptions of the sections, not real test content.

1. CAST and CAST-RStandard

   Graphic Arithmetic

   You work from drawings — a plan, an elevation, a pole or conduit layout, a simple schematic — and answer questions that need numbers taken off them. The arithmetic itself is everyday: adding, subtracting, scaling, percentages. The work is finding the right figures and not misreading a label or a scale.

2. CAST, CAST-R, POSS and MASSStandard

   Mechanical Concepts

   Simple pictures of mechanical arrangements with a short question: which gear turns which way, which pulley takes less effort, where the pressure is highest, which load is more stable. No formulas are needed and nothing is measured; it is about understanding how everyday mechanisms behave.

3. CAST, CAST-R, POSS and MASSStandard

   Reading for Comprehension

   You read passages of the kind of writing the job involves — procedures, safety rules, equipment descriptions, work instructions — and answer questions on each. The wrong options are usually true-sounding statements the passage does not actually support, so the discipline is answering from the text rather than from what you already know.

4. CAST, POSS and MASSStandard

   Mathematical Usage

   Short applied math: convert units, put numbers into a given formula, work out a rate, a percentage or an area. Individually the questions are easy. The section is built around speed, so the practice that matters is doing simple arithmetic quickly and cleanly.

5. CAST-RStandard

   Work Preferences Inventory

   A long questionnaire of statements about work — how you prefer to plan, cooperate, handle routine and deal with pressure — each answered on an agree-to-disagree scale. There are no right answers and nothing to revise; the point of practicing is the format, the pace and answering consistently rather than second-guessing.

6. POSSComplete

   Figural Reasoning

   Sequences and sets of abstract figures where something changes step by step — a shape rotates, a count grows, a shading alternates. You work out the rule and choose the figure that continues it, or the one that does not belong. No words, no numbers, and a very short clock.

7. MASSComplete

   Assembling Objects

   You are shown loose parts — shapes with connection points, or pieces of a cut-up figure — and several pictures of them assembled. Only one is a correct assembly; the others have a part flipped, rotated wrongly or joined at the wrong point. It is mental rotation and spatial visualization, the skill a fitter uses reading an exploded diagram.
