Peer reviews

PrepAI's peer reviews are a two-sided system where you can request feedback on your own solutions and review other people's code, using inline comments, a shared review queue, a reputation score, and a thanks system. Reading and critiquing real code is one of the fastest ways to improve, and this feature makes it a first-class activity rather than an afterthought.

The two sides of a review​

  • Requesting a review. Submit a solution you want feedback on. It enters the review queue where other users (and mentors) can pick it up.
  • Giving a review. Browse the queue, open a submission, and leave inline comments anchored to specific lines, plus an overall assessment.

Inline comments​

Reviews are anchored to the code, not buried in a separate thread. Reviewers comment on the exact lines that matter — a subtle bug, a clearer approach, a missed edge case — so the feedback is concrete and actionable.

Reputation and thanks​

Giving good reviews earns reputation, and authors can send thanks to reviewers who helped. This creates a healthy loop: the people who invest in others' growth are recognised, which keeps the queue moving and the quality high.

Why reviewing makes you better​

  • You see alternative solutions. Reviewing exposes you to approaches you wouldn't have written yourself.
  • You practise reading code. Real engineering work is mostly reading code; reviews build that muscle.
  • You articulate trade-offs. Explaining why one approach is better is exactly what interviewers probe for.

How to use peer reviews well​

  1. Submit early, not perfect. A solution that "works but feels off" gets the most useful feedback.
  2. Review at least as much as you request. The queue only works if reviewing is reciprocal.
  3. Be specific and kind. Anchor comments to lines, suggest concrete improvements, and assume good intent.
  4. Close the loop. Apply the feedback, and send thanks to reviewers who helped.

FAQ​

Who can review my code? Other PrepAI users, including users with the mentor role.

Is there a cost? No — peer reviews are part of the free experience.

Can I review without submitting? Yes. You can pick up submissions from the queue and review them even if you haven't requested a review yourself — and doing so builds your reputation.

How are reviewers recognised? Through reputation earned for quality reviews and explicit thanks from authors.
