Phase 0 · Foundation

Placement Assistant

A preparation operating system for DSA, SQL and CS fundamentals. It answers one question: what should I study right now, and why?

Authentication arrives in the next development session.
Attempts, not checkboxes

Every attempt records hints used, time taken, confidence and the specific mistakes made — so the system knows the difference between having seen a question and being able to solve it.

Revision that adapts

A 1/3/7/14/30-day ladder stretched or compressed by how the last review actually went. Full history is kept; nothing is overwritten.

Transparent mastery

Mastery is a weighted score over independence, consistency, confidence, speed and retention. Every number can be expanded to show exactly why it is what it is.

Readiness, honestly labelled

Company and overall readiness are internal preparation indicators computed from your own tracked data — not a prediction of whether you will clear the interview.
