Slides or Notes: Which Should You Make a Quiz From?

Make your quiz from lecture notes when you want depth, and from slides when you want speed and structure. Notes capture the explanations, examples and asides that never reach a slide, so they produce richer questions. Slides are cleaner and faster to upload, and they mirror how the instructor organized the material, which is often how the exam is organized too. The best move is to combine both: upload the slide deck for the skeleton and your notes for the detail.

Most students have both a slide deck and a page of notes for every class, and quietly wonder which one to actually study from. When the goal is a practice quiz, the answer depends on what each source contains and what you want the quiz to test. Here is how they compare and when to reach for each.

What slides are good at

A slide deck is the instructor's own outline. Every heading is a topic they decided mattered, and the bullets under it are the points they wanted you to leave with. That structure makes slides an excellent source for a quiz that covers the right breadth in the right order. Slides are also fast: you export the deck as a PDF or PPTX and upload it as is, with no cleanup. If you build the quiz from a Google Slides deck or a PowerPoint, the generator reads the text on every slide and turns the bullets into real questions in one pass.

The weakness of slides is that they are compressed on purpose. A bullet that reads "diminishing marginal utility" is a prompt for a spoken explanation, not the explanation itself. A quiz built from slides alone can end up testing whether you recognize the term rather than whether you understand it.

What notes are good at

Your notes hold what was said out loud: the worked example the professor did on the board, the analogy that made a concept click, the aside about what tends to show up on the exam. That is exactly the material that turns a shallow recognition question into one that tests understanding. When you make a quiz from a lecture notes quiz maker, the questions can reach the reasoning behind a term, not just its label.

The trade-off is variability. Notes are only as good as the note-taker, and a sparse or disorganized page produces a thin quiz. If your notes for a given lecture are weak, the slides are the safer source that day.

Side by side

The case for using both

You do not have to choose. Upload the slide deck to set the skeleton, then add your notes so the questions reach the explanations behind each heading. The generator reads all of it as one body of text and writes a quiz that tests both the framework and the detail. For a full exam review, feed in several lectures worth of slides and notes together and build a broader question bank you can pull from over multiple study sessions. When you are training a team rather than studying for a course, the same principle applies inside a corporate learning platform, where a knowledge check built from the training deck plus the trainer's notes measures more than slide recognition.

A simple rule

If you have to pick one source, pick the one that is more complete for that specific class. Great slides plus thin notes: use the slides. Sparse slides plus detailed notes: use the notes. Both solid: combine them and get the best quiz of the three options.

What about a textbook instead?

Slides and notes are the two sources most students weigh, but they are not the only options. The assigned textbook chapter sits between them: more complete than notes and deeper than slides, though longer to read and sometimes broader than what the class actually covered. If the exam follows the lectures closely, slides and notes will match it better than the book. If the professor teaches straight from the text, the chapter is the truest source. When in doubt, generate a short quiz from each and see which one surfaces the questions that feel like your exam.

Frequently asked questions

Should I make a quiz from slides or from my notes?

Use notes when you want depth and application questions, and slides when you want fast, well-structured coverage. Notes hold the spoken explanations and examples that make questions test understanding, while slides mirror the instructor's outline and upload with no cleanup. If both are solid, combine them for a quiz that covers structure and detail at once.

Do slides make good quiz questions on their own?

Slides make good recognition questions because each bullet is a point the instructor chose to include. Their limit is depth: a bullet is a prompt for a spoken explanation, not the explanation itself, so a slides-only quiz can test whether you recognize a term rather than understand it. Adding your notes fixes that gap.

Can I upload slides and notes together?

Yes. A quiz generator reads everything you upload as one body of text, so you can add a slide deck and a page of notes in the same session. The deck supplies the structure and the notes supply the detail, and the resulting questions draw on both. This usually produces a stronger quiz than either source alone.

What file format should I export slides in?

PDF or PPTX both work. In Google Slides or PowerPoint, choose File then Download and save as PDF or PowerPoint, then upload that file. The generator reads the text on every slide either way. Avoid exporting slides as images, since an image has no selectable text for the AI to read.

My notes are messy. Will the quiz still be good?

Messy formatting is fine because the generator reads meaning, not layout. What matters is whether the key terms, examples and facts are present in the text. If your notes are genuinely sparse for that lecture, lean on the slides instead, or combine the two so the slides fill the gaps your notes left.
