Questions
- Do I need a separate subscription per language?
- No. One plan covers every live and beta track. Full-stack developers are exactly who this is for, so per-track pricing would be backwards.
- How is the score calculated?
- Theory answers are graded against a fixed rubric: the model classifies each concept as covered, partial or missing, and our own arithmetic turns that into a percentage. Coding answers run against real tests; 70% of the score is the tests passing and 30% is a code-quality review. Nothing is ever a model's guess at a number.
- What if a grade is wrong?
- Every attempt has a 'This grade is wrong' button. A person reads the dispute and your score is corrected if the grader got it wrong.
- What does the CV comparison actually tell me?
- It reads a job advert, checks each requirement against your CV with a quote showing where it is answered, and splits the shortfall three ways: what you can do but did not write down, what your CV claims that your scores here say you would not survive being asked about, and what is simply a gap. The percentage is our arithmetic over those verdicts, never a number a model made up.
