02 Infection Control Low

Weights re-rank as you add material and answer checks.

01 Drop in what you already have.

Lecture notes, a photo of a whiteboard, half a study guide. Messy is fine — Harbor reads it anyway.

02 See the gaps you can't feel.

A few quick checks split solid from shaky from missing — the ones that quietly cost points.

03 Open Harbor, know your move.

One ranked next thing, every time — so studying starts in seconds instead of stalling.

“My notes are a mess” Good. Messy notes are exactly what Harbor is built to read.

“I don't have time” It takes three minutes and saves you a wasted evening.

“Is this allowed?” Harbor helps you learn before the test. It does not take the test for you.

DHY 252 is waiting for you

Not being ready is expensive. It's the question you skimmed past, the topic you swore you'd come back to, the grade you explain away later.

Three minutes now, or a semester of wondering. Open the class and let the notes review you.
