JourneymanIQ vs Tom Henry: Honest Comparison

What Tom Henry does well

• Calculations workbook with 800+ hand-worked problems across voltage drop, conduit fill, motor sizing, dwelling load, and more.
• Plain-electrician voice. No academic jargon. The explanations sound like a foreman.
• Step-by-step solution methodology that builds muscle memory for hand calculations.
• Affordable. The whole calc workbook costs around $40, less than half a JourneymanIQ subscription.
• Time-tested. The methods work and have for 30+ years.

Where Tom Henry is weakest for full-spectrum prep

• Calculations only. The Calculations workbook doesn’t cover grounding, branch circuits, services, motors-on-the-exam-side, or any non-calc topic.
• No adaptive engine. You drill problems linearly. If you’re strong on voltage drop and weak on conduit fill, you do voltage drop problems anyway.
• Static. Updates lag NEC cycles by months or years.
• Print only. No mobile-first study mode.
• Single-state. Doesn’t address Texas amendments or California amendments specifically.

What JourneymanIQ does well

• Adaptive practice across all six TDLR domains and all four California domains, not just calculations.
• Mobile-first. Study on your phone in 15-minute chunks during lunch breaks.
• Diagnostic that predicts score in 90 seconds, free with no signup.
• Calculator walkthroughs that show the work step-by-step on screen.
• Daily structure. The 30-day plan tells you what to do tonight.

Where the two approaches differ

• Calculations only vs full-exam coverage: Tom Henry is the deepest hand-calc workbook on the market. JourneymanIQ covers all six TDLR domains and all four California domains, with calculator walkthroughs, code-navigation drills, and a 30-day adaptive plan.
• Paper-and-pencil vs adaptive digital: Tom Henry is print, linear, self-paced. JourneymanIQ is mobile-first, surfaces your weak topics first, runs in 15-minute chunks during work breaks.
• Format and pricing: Tom Henry workbooks are one-time print purchases for around $40 each. JourneymanIQ is $49/month or $129 for three months — built for working electricians with a defined exam window. Cancel anytime, your progress stays in your account.

When to pick which

Pick Tom Henry if:

• Calculations are your weakest area.
• You learn best with paper and pencil.
• You want a one-time purchase rather than a subscription.
• You have 60+ days to grind problems.

Pick JourneymanIQ if:

• You need full-spectrum coverage (calculations plus everything else).
• You’re in the last 30 days and need adaptive prioritization.
• You study on a phone during work breaks.
• You want a free diagnostic to see where you stand before committing budget.

Pick both if:

• Calculations are killing you AND you need to study other domains too.
• You want hand-calculation drill (Tom Henry) plus daily adaptive practice (JourneymanIQ).

The bottom line

Tom Henry built the best calculations workbook on the market. If calc is your weak spot, drill his book until problems are automatic. Then move to JourneymanIQ for the rest of the exam: grounding, branch circuits, services, motors, and timed full- length practice. Two tools that complement each other better than either replaces the other.
