Turn Lecture Slides and PDFs Into Practice Tests
Upload slides, readings, or photos of notes and get quizzes, flashcards, and an AI tutor that works from your course material.
College exams lean heavily on two sources: what the professor said in lecture and what was in the assigned reading. Midterms and finals often ask you to apply a concept to a new example, so recognizing a term on a slide is not enough. You need practice answering questions before the exam does it for you.
Where studying in college breaks down
The readings are longer than your week
Three courses can easily assign a few hundred pages a week. Most students skim, then panic before the midterm. Upload a reading as a PDF and BrainLift generates a quiz on its main ideas, so you find out what you actually absorbed and where to go back.
Several finals land at once
When four exams fall in the same week, you cannot give each one a full review. Keep a deck for every course and let spaced repetition handle the scheduling. Cards you know well wait; cards you keep missing come back sooner, across all your classes.
Professors' slides leave gaps
Some slides are just headings and a chart, with the real explanation said out loud. When your notes stop making sense, open the AI tutor chat and ask it to walk through the idea step by step. It can sketch a chart or diagram when a graph explains it better than a paragraph.
What a generated quiz looks like for college
This sample comes from an intro microeconomics lecture on markets.
1. A binding price ceiling set below the equilibrium price causes: A) A surplus B) A shortage (correct) C) No change in quantity D) A rise in the market price Why: At the capped price, buyers want more than sellers are willing to supply.
2. A 10% rise in price leads to a 20% drop in quantity demanded. Demand is: A) Elastic (correct) B) Inelastic C) Unit elastic D) Perfectly inelastic Why: The percentage change in quantity is larger than the percentage change in price, giving an elasticity of 2.
3. Which definition fits opportunity cost? A) The money spent on a purchase B) The value of the next-best alternative given up (correct) C) The total cost of production D) A cost that cannot be recovered Why: Every choice gives up something, and opportunity cost measures the most valuable option you passed on.
| Front | Back |
|---|---|
| Binding price floor (above equilibrium) | Creates a surplus |
| GDP by expenditure | C + I + G + NX |
| Marginal cost | The change in total cost from producing one more unit |
| Law of demand | As price rises, quantity demanded falls, other things equal |
Professors define terms in slightly different ways, so compare generated answers with your lecture notes and syllabus readings.
How it works
- Upload a slide deck or reading as a PDF, photograph your notes, or type a topic.
- Choose a difficulty and question count, and take the quiz to see where you stand.
- Review the flashcards each day; anything you got wrong can become its own mistakes deck.
Study habits that work in college
Treat every lecture as a small test. Within a day, generate ten questions on it and answer them without your notes. A meta-analysis of practice testing found that it generally produced more learning than restudying the same material (Adesope et al., 2017).
Plan finals backward. Give the earliest exam the most time first, while keeping a short spaced review going for the others. Our post on turning a textbook PDF into practice questions shows how to work through long readings, and the finals week study plan has a day-by-day schedule.

FAQ
Can I use it for several courses at the same time?
Yes. Make separate quizzes and decks for each class, and your spaced review will mix in cards from all of them.
What happens to the files I upload?
They are used to generate your quizzes, cards, and tutor answers. Read the privacy policy for how data is stored and handled.
Is it on both web and iPhone?
Yes. BrainLift has an iPhone and iPad app and a web app you can use in any browser.
