# Making practice questions with ChatGPT, and where it breaks

> ChatGPT will write practice questions from notes you paste. It will not check the quote against the page or have a second model answer blind. Here is the gap.

A general assistant can write practice questions from a chapter you paste in. The difference is what happens after it writes them: here, a question that cannot prove where it came from is deleted before you see it.

## What a general assistant does well

- Explains a concept in as many different ways as you need until it lands
- Handles any subject, any format, with no setup
- Good at summarizing, rewording and tutoring conversationally
- Will happily write a handful of questions from text you paste in

## Where it stops being enough for exam practice

- Nothing checks the answer key. A confident wrong key is indistinguishable from a right one until it costs you points.
- Citations to a page number are generated text, not a lookup. There is no verification step that the line is on that page.
- Context limits make a 900 page book impractical to paste, and chunking it by hand is the work you were trying to avoid.
- There is no score, no chapter mastery, no review queue and no record of which questions you have already seen.
- Deduplication is manual, so long runs repeat the same idea in different words.

## What this service adds on top of the same models

MedUni Exam calls large language models too. The product is the pipeline around them: the document is split and stored page by page, every question must carry verbatim quotes, the server checks those quotes against the stored page, and a second model from a different family answers the question blind and has to agree with the key. Then there is the study side: grading, A to F, mastery per chapter, spaced review, exams weighted toward weak topics, and a tutor that answers only from your document. See [how it works](https://meduniexam.com/how-it-works.md).

|  | General assistant | MedUni Exam |
| --- | --- | --- |
| Input size | What fits in a conversation | Whole textbooks, uploaded in parts |
| Page citations | Written by the model | Checked against the stored page text |
| Answer key | Unchecked | Blind second-model check on a different family |
| Scanned pages | Depends on the tool | Read with optical character recognition |
| Grading and tracking | None | Grades, chapter mastery, review queue, debrief |

## Using both

Ask an assistant to explain the mechanism you keep getting wrong. Come here when you want to be tested on the chapter your department set, with questions whose sources you can open and read.
