The detail on each

Mike Holt

Format: Books + video library + practice tests

Price: $200-600 depending on bundle

Strongest: Foundational NEC video library. Massive depth.

Weakness: Static. No adaptive engine. Volume can overwhelm.

Best for: Apprentices and candidates with 90+ days who learn best from video.

Tom Henry

Format: Calculation workbooks (print)

Price: $40-80 per workbook

Strongest: Hand-calculation drill methodology. Plain-electrician voice.

Weakness: Calculations only. No coverage of non-calc domains.

Best for: Anyone with weak calculation skills. Pair with another tool for full coverage.

BuildForce / similar online courses

Format: Self-paced video course + practice tests

Price: $150-400 per course

Strongest: Texas-specific. Streaming access.

Weakness: Static practice tests. Limited adaptive features.

Best for: Candidates who want a structured course but don’t need a full Mike Holt library.

Ray Holder

Format: Texas-specific prep books + workbooks

Price: $50-150 per book

Strongest: Texas-specific. Long-running brand authority for TDLR prep.

Weakness: Older code editions in some print runs. Verify before purchase.

Best for: Candidates who want a Texas-specific print resource.

JourneymanIQ

Format: Adaptive practice + 4 calculators + 170 drills + Wave Mock + 30-day plan

Price: $49/month or $129/3-months

Strongest: Adaptive engine surfaces your weakest topics first. Index keyword drills (no other platform has these). The Wave Mock 5-pass exam-strategy simulator. Mobile-first. Free diagnostic shows weak topics in 90 seconds.

Weakness: Built for the focused 30 to 60-day window. Apprentices with 6+ months and zero NEC knowledge benefit from pairing with a foundational video library.

Best for: Working electricians prepping for their licensing exam: apprentices on their first attempt, retakers fixing what cost them last time, master candidates building on existing knowledge.

How to pick

If you have 6+ months and are starting from zero

Mike Holt foundational set. Watch the videos. Take notes. Build understanding before you build speed.

If you have 30-60 days and have studied before

JourneymanIQ for the daily structure and adaptive surfacing. Tom Henry workbook on the side if calculations are your weak area.

If you failed the exam before

Read your TDLR score report. The bottom-2 domains are your target. Build a retake plan around them. JourneymanIQ’s adaptive engine is built for this case; Mike Holt is overkill if you already know most of the material; Tom Henry helps if calculations are the problem.

If budget is tight

Tom Henry workbook ($40) plus JourneymanIQ’s free diagnostic covers a lot of ground for under $50. If you don’t need full-platform features, the diagnostic alone tells you where you stand.

What we don’t recommend

  • Free PDFs from random websites. Most are based on old NEC editions and contain rule changes that don’t apply to current exams.
  • YouTube lectures from unverified instructors. Quality varies wildly. Mike Holt’s YouTube is fine; random channel #47 may be teaching outdated rules.
  • Brain dumps and 'real exam questions' sites. These are typically inaccurate, sometimes copyright violations of the actual exam.

Take the diagnostic before deciding

The 90-second diagnostic shows your weak topics. From there you can choose foundational learning, calculation drilling, or adaptive practice, depending on what the gap looks like.
