Frequently asked questions
Quick answers about Prepshotz - what it is, what's free during beta, the skills you can practice, and how grading works.
01 What is Prepshotz?
Prepshotz is a hands-on practice engine for technical skills. You write real code in your browser and it is graded automatically by running it - starting with SQL, with more skills rolling out during the beta.
02 Is Prepshotz free?
Yes. It is completely free while we are in beta. There is no pricing page yet, and no credit card required.
03 What skills can I practice right now?
SQL is live today. Python, JavaScript, Java, C++, C#, data analysis and algorithms are rolling out during the beta.
04 How does grading work?
Your code is graded by running it. For SQL, your query runs against a real database and the result is compared to the expected answer. For code, your solution must pass a test suite. It is objective - no multiple choice, no opinion.
05 Do I need to install anything?
No. Everything runs in your browser - the editor, the database, and the grading. You just need a modern browser.
06 How is Prepshotz different from ChatGPT?
ChatGPT can explain a concept, but it cannot run your code against real tests or remember what you keep getting wrong. Prepshotz runs and grades your real work and brings back your weak spots.
07 How is it different from LeetCode or other practice sites?
Those run and grade code, but the catalog is fixed. Prepshotz is built to shape practice around your goal and adapt to your mistakes - starting with curated SQL today and expanding through beta.
08 Do I need an account?
Yes - you sign in with Google to save your progress. It takes a few seconds and is free.
09 Is my data safe?
Yes. We collect only what we need to run your account and progress, and you can export or delete your data. See our Privacy Policy.
10 When will more skills and personalization arrive?
They are rolling out during the beta. Start free now and you will get new skills as they land.
