About the Graphic Problem Solving section
Graphic Problem Solving is the first of the four tests in EEI's TECH battery, the one utilities use for technician jobs such as lab, relay, telecom, drafting and estimating. EEI's brochure describes it in one sentence: it measures the ability to use numerical information presented in illustrations to solve practical arithmetic problems. It does not publish how many questions there are or how long you get.
That description is close to CAST's Graphic Arithmetic, and the habits are the same: read the question first, find exactly the figures it needs, check the units and the scale, then do simple arithmetic carefully. Our TECH version uses illustrations only — dimensioned plans, a sump tank in plan and elevation, a cable route measured off a scaled drawing, a tower with its feed runs, charts and a substation one-line — rather than tables.
Because EEI publishes no timing, our timed run is our own: 16 questions in 30 minutes, the published pace of CAST's Graphic Arithmetic. Treat it as a sensible practice pace, not a statement about the real test. Every question is generated fresh and checked by a script that re-solves it from the figures printed on the illustration.
Tips from practice
- Read the question before the drawing, so you go looking for specific figures rather than reading everything.
- Check what the printed numbers measure. On a scaled drawing they are sheet inches, not feet on the ground.
- Write down each figure as you take it off the illustration, with its unit.
- If an answer is far from a quick estimate, you have probably used the wrong figure, not done bad arithmetic.
Common questions
- How many Graphic Problem Solving questions are on the TECH test?
- EEI does not publish a count or a time limit for it. Its brochure gives those figures only for Mechanical Concepts. Numbers you see elsewhere usually match EEI's shorter practice exercises, not the real test. Our 16-in-30 run is our own practice length.
- Can I use a calculator?
- EEI's TECH brochure says nothing either way, so it is the employer's rule on the day. Practice both ways: our drill has an on-screen calculator you can switch off.
