How it is judged

Every answer goes through the real judge.

The same path for a placement drill, a course lesson, a college test or a fest contest.

  1. 1

    You write it

    In the workspace, in your language. Run it on the sample as often as you like.

  2. 2

    We compile it

    On our judge, with the same compiler every time. A compile error is never counted as a try.

  3. 3

    Hidden tests run

    Edge cases, big inputs and time limits you cannot see, each in its own sandbox.

  4. 4

    The verdict lands

    Accepted, or exactly which kind of failure. It goes straight to your record and your report card.

While you practise

Run, get help, keep your record.

Run, then submit

Check on the sample first

Run your code on the sample, then submit for the hidden tests when you are ready.

Help when stuck

AI hints, editorials, discussions

A nudge without the answer, then see how others solved it. All switched off in contests and tests.

Personal insights on your dashboard, a streak to keep, and a public profile to show your work, or keep it private.

Courses

Learn by doing. Every lesson is judged.

18 courses with a short explanation, code you change and run, a quick check, then problems the judge checks. Checkpoints, a final test and a certificate anyone can verify.

All courses

Open courses

How a course works

Short lessons. Real checks.

  1. Read a little

    A short explanation with an example, written for students, not for experts.

  2. Change it and run it

    Edit the example code in the lesson and run it to see what changes.

  3. Check, then solve

    A quick check, then practice problems the judge checks on hidden tests.

  4. Checkpoints and a final test

    Pass them to finish the course and get your certificate.

Certificate

Finish a course, get a certificate anyone can verify.

Your name, the course, your final-test and checkpoint scores, the units and skills. A QR code and a public link let a recruiter or a college check it is real.

Sample Faurus certificate, front: Student Name has completed SQL Mastery 2026 with distinctionSample Faurus certificate, back: the course units, skills, scores and a QR code to verify it

A sample: the name and ID are placeholders.

For colleges and institutes

One batch, start to finish. A report card for every student.

A private space for your institute, timed and proctored tests, assignments and contests. Every attempt of every student is tracked, so teachers see exactly where each one stands.

How a pilot runs

  1. A short call

    We agree the batch, the dates and what you want to measure.

  2. Your space goes live

    Years, sections, batches and clubs. Nothing crosses between institutes, and your students stay off public leaderboards.

  3. Two weeks of real work

    Practice on real tools, assignments, and a timed test with full-screen and tab checks.

  4. A report card for every student

    Scores, attempts, strengths and gaps for each student, and personal insights they see too.

What you see

The real screens. Sample data.

A teacher's report card for one student, the results sheet for the whole batch, and the report card each student sees on their own dashboard.

FAQ

Questions, answered.

Anything else? Write to ceo@faurus.app.

Is Pro a subscription?

No. Pro is a one-time pass for 1, 2, 3 or 4 months, with no auto-debit. When it ends you are back on the free plan, unless you buy another pass.

What does a pilot cost?

₹4,999 for one batch of 30 to 60 students for two weeks. If you continue, the ₹4,999 is credited in full to your plan. Email ceo@faurus.app or call +91 88744 97809 to book one.

Is the SQL a real database?

Yes. SQL problems run on a real MariaDB, so you write MySQL-compatible SQL. MongoDB and Redis problems run on real instances too.

Which languages and tools can I use?

For algorithms: C, C++, Java, Python, JavaScript, TypeScript, Go, Rust, Ruby, PHP and R. Every other skill uses its real tool: SQL, MongoDB and Redis on database servers, HTML, CSS and React in a browser, Node on a server, Linux, Bash, Git and Docker in a shell, and Python with NumPy, Pandas, scikit-learn and PyTorch for data and AI.

What are Faurus courses?

18 courses you learn by doing, from SQL, DSA and Python to web development, cloud and DevOps, aptitude, software engineering and AI. Each lesson has a short explanation, code you change and run, a quick check and problems the judge checks. Finish the checkpoints and the final test for a certificate anyone can verify. See the courses.

Is there help when I am stuck?

Yes. AI hints give you a nudge without the answer, and editorials and discussions show how others solved it. All of them switch off in contests and tests.

How does proctoring work?

For tests you can turn on full screen and tab-switch tracking for every student, and every attempt is timed. Exam mode switches off hints, editorials and discussions. Camera, microphone and screen are never recorded; we only note when a student leaves the test and comes back.

Will it hold up when a whole batch submits at once?

Yes. In our load test, one server judged 2,500 submissions in 80.5 seconds, all of them correctly, with nothing left in the queue.

Do our students' scores stay private?

Your institute's space is private and nothing crosses between institutes. Your students stay off public leaderboards unless they opt in, and you can switch public mode off for your institute.

What is the refund policy?

The exact conditions are on our refund policy page. For anything it doesn't cover, write to ceo@faurus.app.
