IBEW Apprenticeship · Aptitude Test Prep

The test between you and the trade.

Before any electrical apprenticeship interview, there's an aptitude test — algebra, number series, and mechanical reasoning, on a clock. Most people walk in cold and find out what it looks like the moment it starts. You won't.

Section 1 · Number SeriesQ.02 / 25

What is the next number in this sequence?  3, 7, 15, 31, …

Worked solution
  1. Differences between terms: 3→7 is +4, 7→15 is +8, 15→31 is +16.
  2. The difference doubles each step: 4 → 8 → 16.
  3. Next difference is +32.  31 + 32 = 63.

Every one of the 25 problems in the guide is worked through like this — because knowing the answer is worthless if you can't reproduce the method under a clock. Get all 25 ↓

Why this works

RULE 01

Worked, not answered

An answer key tells you what. These show you how — every step, so you can reproduce the method on a problem you've never seen.

RULE 02

Exam order, exam language

Sections mirror how the aptitude test is actually structured — series, algebra, ratios, data, geometry — so nothing surprises you on the day.

RULE 03

Job-site math

Conduit runs, cable waste, panel tolerances, crew hours. The same numbers you'll use in the trade — which is exactly why the exam tests them.

RULE 04

Built for the clock

Short, dense, no filler. You can work the whole guide in a weekend and re-drill the sections that bite.

Straight answers

What is the electrical apprenticeship aptitude test?
A timed entrance exam used by electrical apprenticeship programs to screen applicants before the interview. It covers algebra and functions, number series, and mechanical reasoning. Score well and you interview; score poorly and you wait to retest.
Is Volt Prep affiliated with the IBEW?
No. Volt Prep Academy is an independent study resource. It is not affiliated with, sponsored by, or endorsed by the IBEW, NECA, or the Electrical Training Alliance. All questions are original practice material written to mirror the style and difficulty of the exam.
What exactly do I get?
Instant-download PDFs. The Aptitude guide: 25 fully worked problems across the five exam areas. The Mechanical Blueprint: the eight governing concepts behind mechanical-reasoning questions, stated as rules you can apply to any variation. Study on your phone, tablet, or print them.
What's the refund policy?
Because these are instant digital downloads, all sales are final. Try the free sample question above first — that's exactly what the guide is like inside.
