About QuizPrep

QuizPrep helps you prepare for Python coding interviews the way a good teacher would: not by dumping answers on you, but by explaining the insight behind each solution — the pattern to recognize, why it works, and what it costs in time and space.

Each question gives you a clean problem statement, a browser editor to sketch your approach, and — when you're ready — an idiomatic Python solution with a full walkthrough. We deliberately keep the focus on understanding over volume.

How it works

• Pick a question from any category — arrays, hash tables, two pointers, trees, recursion, dynamic programming, and more.
• Try it in the editor. Nothing is graded automatically; the goal is to think it through.
• Reveal the solution to check yourself and absorb the explanation.

Pricing

A generous set of questions is free forever. Premium ($14.99/month, $99/year, or $99/year in crypto) unlocks every solution and explanation. It's a fraction of what the big platforms charge.
