WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Concept against study, from your notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

This tool splits the text you paste by rule and returns two sided cards. It cannot describe a study you did not write down, so what comes back is exactly as complete as your notes.
Learn each concept in both directions
Questions describe a scenario and ask for the term, and also give a term and ask for an example. A card that only runs one way leaves you fluent in half the exam. Making the reverse card takes seconds and it is the single most efficient adjustment available in this unit.
Heuristics are useful shortcuts, not stupidity
The availability and representativeness shortcuts exist because they usually work quickly enough. They fail in predictable circumstances, and questions describe exactly those circumstances. Framing them as errors rather than as trade-offs makes the failures harder to predict.
Working memory has a small capacity and one workaround
Working memory holds a few items briefly while you manipulate them. Chunking raises the effective limit by grouping items into meaningful units, which is why a phone number is easier in blocks. That mechanism appears in questions about learning strategies as well as about memory itself.
Schemas explain both good and bad remembering
A schema speeds up understanding by supplying expectations, and the same expectations insert details that were never there. Memory reconstruction questions turn on this, and an answer that mentions both the benefit and the cost demonstrates the concept rather than the label.
This unit describes the study habits that fail
Rereading feels effective because familiarity is easy to mistake for knowledge, a gap Karpicke and Roediger measured directly on delayed tests. Students in this course have the unusual advantage of being taught, in a graded unit, why their default revision method underperforms. Using that on this very unit is the obvious move.

| Shortcut | Why it exists | Where it fails |
|---|---|---|
| Availability | Easy examples usually are common | Vivid rare events feel frequent |
| Representativeness | Typical cases usually are likely | Ignores base rates |
| Anchoring | A starting point speeds estimation | The anchor was arbitrary |
| Confirmation bias | Consistency is cheap to maintain | Evidence against is undercounted |
| Functional fixedness | Usual uses are usually right | Blocks a novel solution |
| Schema | Expectations speed understanding | Inserts details never present |
What is AP Psychology Unit 2?
Cognition: memory, thinking, problem solving, language and the heuristics and biases that shape all of them.
How is it different from Unit 1?
Unit 1 is a volume problem. Here almost every concept is defined by an experiment, and questions often describe the study instead of naming the term.
Why should cards run in both directions?
Because questions go both ways: a scenario asking for the term, and a term asking for an example. A one way card prepares you for half the exam.
Are heuristics just errors?
No. They exist because they usually work fast enough. They fail in predictable circumstances, and those circumstances are what questions describe.
What is chunking?
Grouping items into meaningful units so working memory can hold more. It is why a long number is easier to remember in blocks.
How do schemas cause memory errors?
By supplying expectations. The same expectations that speed understanding insert details that were never in the original event.
