Frequently asked questions
That’s what AlgoDrill is built for. You write the code line by line from memory, work on the lines you forget, and come back to the problem through spaced repetition. Each review helps build the muscle memory to write the solution yourself.
“DSA used to feel like a nightmare because I'd solve problems and forget them after a week. Now it feels like muscle memory. I actually understand the patterns and can recall them naturally. Thanks a lot 🙌❤”
Yes. The course teaches data structures and patterns from first principles, with visual walkthroughs that show why an approach works and questions that check your understanding.
For each problem, the Study tab walks you through the thought process from the first observation to brute force, then the optimal approach. Guided implementation steps show how those ideas become code, highlighting the lines and explaining each decision. You work through edge cases and complexity too. When you start practicing, you know what you’re trying to write and why it belongs in the solution.
ChatGPT and Claude can explain a solution until it makes sense. The real test is whether you can still write it a week later with the chat closed. AlgoDrill gives you structured practice for exactly that. You write the code from memory, get feedback on the lines you miss, and revisit problems through spaced repetition. You’re paying for a practice system that builds fluency beyond the explanation, with your weak spots and progress tracked across sessions.
If you keep rewatching the same NeetCode videos or revisiting LeetCode editorials because you’ve forgotten how to solve the problem, this is for you. Bring what you’ve already learned into AlgoDrill, including your own solutions, and practice the steps you still struggle to write. You keep your existing prep and make that work count the next time you face the problem.
Yes. Paste your complete solution and AlgoDrill turns it into a recall drill with explanations. You practice the code you actually wrote, so the work you’ve already done becomes something you can keep reviewing. Free includes 5 custom drill generations. Pro includes unlimited generations.
Free gives you 10 starter problems, free course lessons, and 5 custom drill generations. Pro unlocks the full problem library, including all of LeetCode 75 and NeetCode 150, the complete visual interview course, and unlimited custom drill generations. You can study and drill the whole set you’re preparing for, with explanations for unfamiliar patterns and room to keep adding your own solutions.
