About Keypath Labs

Keypath Labs builds Quizzler, a lightweight practice space for students, engineers, and developers who want to sharpen their circuits and networking fundamentals without friction. No accounts are required—open the site and start working through problems right away.

What we care about

• Clear, focused questions that feel like the real exam room.
• Fast load times and a distraction-free interface.
• Practical explanations that reinforce the underlying concepts.

How we keep the lights on

You may see Google Ads placements. They help us keep Quizzler free to use while we continue to add more practice sets and visualizations.
