Guesswork

No streaks, no busywork, no hoping.

Proof it was the right work.

Rereading what feels familiar isn't studying. It's hoping. Harbor replaces the guessing with a precise map of where you actually stand.

A Harbor Readiness Map for BIO 201, elements grouped by topic with readiness scores.
The map

Your whole course, mapped.

Harbor turns your notes, slides, and review guides into a Readiness Map — small, testable elements, each traced to its source and weighted by exam impact. Nothing arrives unexplained.

The score

One number that tells the truth.

See what's solid, what's shaky, and where a focused hour moves you most. Answer a question and watch it respond — live, on your own class.
