Get it right and it moves further away.

Soar is classroom software that runs on your computer. This page covers only the learning side of it: the part in charge of remembering.

If you haven't reviewed something, it says you haven't.

Words and questions line up in one queue, ordered by when you're about to forget. Flip through the stack and the day is done.

Today's review in Study: a word card, flipped, with four difficulty ratings below it
The same screen inside the software — terms and class questions from the demo course, in one queue

The “minutes” on those keys are gone

In an early version the four rating keys read “Again 1 min · A bit hard 6 min · Got it 10 min · Too easy 8 days”: two different units in one row. Those three minute figures came from the scheduling library's default “learning steps,” copied straight through; they predicted nothing about your memory.

Learning steps assume you sit down and drill for an hour. This queue comes around once a day, so those 10 minutes never actually arrive. Since we switched them off in August 2026, the four keys read 1 / 2 / 3 / 8 days.

Any more won't fit, so we “chunk” scattered bits into packages.

chunks

The harder it is to recall, the better it sticks. That is memory science.

We keep your streak too, but it never nags, never ranks, and says nothing when it breaks.

The same card, asked a different way

Recognize it, meaning → word, multiple choice, fill in the blank: it rotates with each review, then starts over from the top.

Multiple-choice distractors are pulled from your own word bank, across all courses. Fill in the blank only comes up when the word has an explanation from class and that explanation uses the word itself.

After a wrong answer

Wrong answers graduate

The wrong-answer book is a ladder. Get it right twice and it graduates out.

Wrong-answer book

Which memory is the small, live, seconds-long workspace?

You picked “sensory memory

You picked “sensory memory”, but that's the millisecond-long input gate; the “small, live, seconds-long workspace” is working memory. You mistook the doorway for the desk.

Test me again

Which is the active, moment-to-moment workspace?

You picked “short-term memory

You picked “short-term memory”, an older term often confused with working memory. The difference: short-term memory only holds; working memory also manipulates.

Test me again

Chunking directly expands the effective capacity of what?

You picked “attention span

You picked “attention span”. Chunking does rely on attention, but what it expands is how many units working memory can hold at once (turning 1-9-4-9 into “1949”).

Test me again

An emptying book is hope, not a pillory.

If you haven't reviewed it, it says “not reviewed yet.”

How much stuck

Honest mastery

A star's color is its concept cluster; the gray ones are the ground ahead you haven't touched yet. Mastery lives in the panel that opens when you tap one.

cognitive load

Mastery: not reviewed yet

color = concept cluster · size = connections · gray = not touched yet

A new concept is a new concept. We won't hand you a fake “50%”.

Those numbers move with you

“Review intensity” has three settings. Tighten it and “Easy” shrinks from 8 days to 4; loosen it and it stretches to 16.

The default setting is the 1 / 2 / 3 / 8 days printed on the keys.

Loose 16 days Default 8 days Tight 4 days

How do chunks and working memory relate?

Chunking packs scattered bits into one meaningful unit1, directly expanding how much working memory can hold at once2.

Tap a superscript to see which source it's based on.

It flagged this itself, from outside your sources:The term “chunk” was first proposed by psychologist George Miller in 1956.

It won't pretend you've reviewed it

The colors, the numbers, that progress bar: every one of them comes from something you actually did. Where you haven't, it stays empty.
