Reading the PDF twice is not the same as knowing it.
PDFs are dense. Whether it's a 200-page textbook chapter, a professor's lecture slides, or a research paper full of methodology, re-reading it feels productive but rarely produces lasting retention. The information goes in one pass and leaks out before the exam.
The fix is retrieval practice — forcing yourself to produce the knowledge from memory. Learnlo converts your PDF into a written-answer exam so you can actually test yourself, not just re-read.

Example — AI Exam Grading
Question
Describe the role of the electron transport chain in cellular respiration.
Student Answer
The electron transport chain uses electrons from NADH and FADH2 to pump protons across the mitochondrial membrane, creating a gradient used to make ATP.
AI Grading Feedback
8 / 10Strong answer — you correctly identified the electron donors (NADH and FADH₂), proton pumping, and ATP synthesis. For full marks, mention that the chain is embedded in the inner mitochondrial membrane and that oxygen is the final electron acceptor, forming water.
Frequently Asked Questions
What is the maximum PDF size I can upload?
Free users can upload PDFs up to 10 MB. Plus and Pro users get higher limits. For very long documents, Learnlo will focus the exam on the most important concepts while noting if any content was summarised.
Does it work with scanned PDFs?
Yes, for most scanned PDFs. Learnlo applies OCR to extract text from scanned documents. Image quality affects accuracy — clear scans work best.
Can I upload professor slides (PowerPoint exported as PDF)?
Yes. Slide decks exported as PDF are one of the most common uploads. Learnlo handles them well — it understands the sparse, bullet-point format of slides.
What kinds of questions does it generate from a PDF?
Written-answer questions that require you to explain, describe, compare, or analyse concepts from your PDF. The depth and difficulty match the content level of your document.
How many practice exams can I generate from one PDF?
Free users get 1 exam per pack. Plus users get up to 3 exams per pack (including adaptive follow-up exams targeting weak topics). Pro users get up to 5.
Will the exam cover the whole PDF?
For very long PDFs, Learnlo focuses on the highest-importance concepts. All uploads include a summary so you can see what was covered. You can also generate additional packs from specific sections if needed.
Can I get flashcards and a quiz from the same PDF?
Yes. Every pack includes flashcards, a multiple-choice quiz, practice exam, summary, notes, and mind map — all generated from the same PDF upload.
