A practice engine, not a course library
Prepshotz exists because most online learning is watch-not-do: videos and quizzes that feel productive but never test whether you can actually do the work. We built the opposite - a practice engine where you write real code and it's graded by running it, the same way the real work is judged.
The problem we're fixing
Watching a tutorial is not the same as being able to do the thing. Multiple-choice can't tell you if your code works. We wanted practice that is real and graded objectively.
Our approach
Objective, execution-based grading: your work runs, and the result decides. It's honest, it's the real bar, and it's what makes the feedback trustworthy.
Where we are
In beta, free, shipping new skills regularly, and building in the open. SQL today; more soon.
// Who it's for
Built for people who want to do the work.
Prepshotz is for anyone building real technical skill and tired of passive learning. You don't watch someone else solve it - you write the code, run it, and find out whether it works.
- Self-taught developers who want proof they can do the work, not just tutorials watched.
- Computer-science students bridging coursework and real, hands-on practice.
- Job seekers preparing for technical interviews and take-home tasks.
- Working engineers sharpening a specific skill - SQL today, more rolling out.
// Good to know
The questions people ask.
01 Why does Prepshotz exist?
Most online learning is watch-not-do - videos and multiple-choice that feel productive but never prove you can do the work. Prepshotz exists to flip that: you write real code and it is graded by running it, so practice matches how the job actually judges you.
02 Who is Prepshotz for?
Anyone building real technical skill - self-taught developers, computer-science students, people prepping for technical interviews, and working engineers sharpening a specific skill. If you would rather prove you can do something than watch someone else do it, it is for you.
03 Is Prepshotz a course or a practice tool?
A practice tool, not a course. There are no video lectures to sit through - you work real tasks in a live in-browser editor, run them, and get graded on the result. Short concept primers and hints sit inside the practice, not in place of it.
04 How do I know the grading is fair?
Because nothing rides on opinion. Your SQL runs against a real database and the result is compared to the expected answer; your code has to pass a test suite. It either runs and matches or it does not - the same bar the real work uses.
