How to Make a Study Guide From Notes, Slides, and PDFs
A study guide should not be a prettier version of your notes. If building it means copying lecture slides into one giant document, you may finish with something organized but still have no idea what you can actually recall.
The best study guides reduce a large body of material into prompts that force you to think.
Step 1: Gather before you summarize
Start by collecting the full exam universe: lecture notes, slide decks, assigned readings, PDFs, problem sets, previous quizzes, and any guidance from the instructor. Do not study yet. First make sure you know what material exists.
If your course files are spread across email, a learning platform, Downloads, and shared drives, create one temporary home for the exam. The container can be a folder, a cloud directory, or a private Kahana hub if you want PDFs, documents, links, videos, and notes in one place. The point is to remove the scavenger hunt before the actual studying starts.
Step 2: Organize by concepts, not file type
Do not create sections called Slides, Notes, and Readings. Exams usually test ideas, not where the ideas came from. Organize around topics, units, frameworks, formulas, cases, or learning objectives.
For each topic, combine the relevant evidence from different sources. Your lecture note may explain the professor’s emphasis, while the textbook gives the definition and a practice problem exposes where you are confused.
Step 3: Convert information into questions
Cornell’s Learning Strategies Center emphasizes retrieval practice: actively recalling information rather than simply rereading it. So turn each section of your guide into prompts.
- Instead of ‘Four stages of X,’ write: ‘What are the four stages of X, and what changes between each stage?’
- Instead of copying a formula, write: ‘When should this formula be used, and what does each variable represent?’
- Instead of pasting a case summary, write: ‘Why did this case produce a different outcome from the previous one?’
A good guide contains fewer complete answers than you expect. It creates opportunities to retrieve the answers.
Step 4: Add an error section
The highest-value part of a study guide is often the material you got wrong. Keep a running section called ‘Things I Keep Missing.’ Every time you fail a practice question, misunderstand a concept, or confuse two terms, add it there.
This prevents the comfortable habit of repeatedly reviewing what you already know.
Step 5: Study the guide in multiple passes
Cornell also recommends spaced practice rather than cramming. Use your guide more than once, with some time between sessions. On the first pass, identify gaps. On the next pass, answer prompts without looking. Later, mix topics together so you have to decide which concept or method applies.
A useful final format
For each major topic, your finished study guide can contain:
- a one-sentence overview
- five to ten retrieval questions
- one diagram or model if relevant
- common mistakes
- one application problem
- links back to the source material
If your study guide makes it easy to reread everything, it may be too passive. If it makes it easy to discover what you cannot yet explain, it is doing its job.
