If you’re preparing for your electrical licensing exam, you already know where most people struggle: calculation questions. They’re time-consuming, complex, and one small mistake can blow up your entire answer.

That’s exactly why we built the AI Tutor — to walk you through these questions step by step, help you understand the logic, and actually retain what you’re doing. It's designed to work like an instructor sitting next to you — except it's available 24/7.

Focus on the Topics That Matter Most

When you launch the AI Tutor, you choose the exact topic you want to work on. No random quizzes. No generic material. Just the NEC topics that show up again and again on exam day:

And more.

Learn the Way That Works for You

Not everyone learns the same way — and that’s the point. With the AI Tutor, you control how much help you get and how fast things move. You can:

Change difficulty on the fly
If the question is too easy or too hard, just say so.

Adjust how much help you get
Want hints? Want to try on your own first? You decide.


Ask why an answer is right
Understanding the why behind each answer is what helps you retain it.


Learn from your mistakes
Got something wrong? The AI will catch it and walk you through the correction.

This is what makes the AI Tutor different from anything else out there — it adapts to you.
