How to Make a Cheat Sheet That Actually Helps You Learn
To learn from a cheat sheet, build it from memory first, fill the gaps from your notes, then test yourself. What the research says, with steps and templates.
A cheat sheet helps you learn when building it makes you recall and prioritize. Start from a blank page and write what you remember, fill the gaps from your notes, cut what you already know, and then test yourself with the sheet covered. A sheet copied straight from your notes is mostly a lookup tool.
Be skeptical of the common claim that making a sheet is enough by itself. A 2016 paper in *Computer Science Education* reviewed the research and called it "not decisive" on whether crib sheets improve scores or learning. Several of the studies it covers found no gain in exam scores, and one concluded that preparing a sheet did not by itself improve learning. The stronger evidence is for the techniques you can build into the process, especially self-testing.
This guide covers how to build cheat sheets and formula sheets that make you practice, whether your professor allows them on exams or not.
What Makes a Cheat Sheet Useful for Learning
The sheet itself isn't what does the work. Three things you can do while building it are what help.
Retrieval Practice
When you sit down to build a cheat sheet, you naturally start by trying to recall what's important. Before you open your notes, you're already mentally scanning the course material and pulling concepts from memory. This is active recall in action. A major 2013 review by John Dunlosky and colleagues rated practice testing as one of its two high-utility study techniques. Close your notes first, because you only get this benefit if you actually try to recall.
Elaborative Processing
Condensing a full lecture into a few key lines forces you to process information deeply. You can't just copy-paste your notes onto a cheat sheet (well, you can, but it won't fit and it won't help). You have to understand concepts well enough to express them in compressed form. If you can't compress one, that tells you what to go back and study.
Organization and Categorization
Deciding how to structure your cheat sheet, including how to group related formulas and order concepts by topic, makes you think about how the material fits together. It also pays off on exam day, because you can find things faster.
The Two Types of Cheat Sheets
Not all cheat sheets serve the same purpose. Understanding which type you need determines how you should build it.
Formula Sheets
Formula sheets are reference documents containing equations, constants, conversion factors, and mathematical relationships. They're common in STEM courses: physics, chemistry, engineering, statistics, and calculus.
A good formula sheet isn't just a list of equations. It includes:
- The equation itself
- What each variable represents
- When to use it (the conditions or problem types)
- Units for each variable
- Common pitfalls or edge cases
Example: Instead of just writing F = ma, a useful formula sheet entry looks like:
Newton's Second Law: F = ma F = net force (N), m = mass (kg), a = acceleration (m/s^2) Use when: finding acceleration of an object with known mass and forces Note: F is NET force - sum all forces first, including friction
Concept Cheat Sheets
Concept cheat sheets summarize ideas, definitions, processes, and relationships. They're useful for courses like biology, psychology, history, business, and law.
These focus on:
- Key definitions in your own words
- Comparisons between similar concepts
- Process flows and decision trees
- Mnemonics and memory aids
- Connections between topics
How to Make a Cheat Sheet: Step by Step
Step 1: Identify What You Don't Know
This is where most students go wrong. They start by opening their textbook to page one and copying everything sequentially. Instead, start with what you don't know.
Take a blank page and try to write down everything you remember about the course from memory. Don't look at your notes. Spend 15-20 minutes on this. The gaps - the places where you draw a blank or feel uncertain - are exactly what should go on your cheat sheet.
If you've been studying with flashcards, you already know which cards you consistently get wrong. Those topics belong on your cheat sheet.
Step 2: Prioritize Ruthlessly
You don't have unlimited space. Even if your professor allows a full page, you need to make every line count.
Prioritize by asking:
- What concepts appear most frequently on practice exams?
- What topics did the professor emphasize or repeat?
- What do I consistently forget or confuse?
- What formulas can I derive from other formulas? (Skip the derivable ones)
Cut anything you already know cold. If you can recall it without looking, it doesn't need space on your sheet.
Step 3: Organize by Theme, Not by Chapter
Textbook chapters are organized by the author's logic. Your cheat sheet should be organized by your logic - specifically, by how the exam will test you.
Group related concepts together even if they were taught weeks apart. In a physics course, put all the energy equations together (kinetic, potential, work-energy theorem, conservation of energy) rather than scattering them across "Chapter 5" and "Chapter 7" sections.
This organization mirrors how problems actually appear on exams and helps you quickly locate what you need.
Step 4: Use Visual Hierarchy
A wall of text in the same font size is useless under exam pressure. Use visual structure:
- Bold key terms and formula names
- Use boxes or borders around the most critical items
- Color-code by topic (if allowed)
- Leave white space between sections - cramming everything together makes it harder to scan
- Use arrows to show relationships between concepts
Step 5: Add Context, Not Just Content
The difference between a useless cheat sheet and a great one is context.
Useless: PV = nRT
Useful: PV = nRT (ideal gas only, use Van der Waals for real gases at high P or low T)
Useless: Mitosis: PMAT
Useful: Mitosis: Prophase (chromosomes condense) → Metaphase (align at center) → Anaphase (pull apart) → Telophase (nuclear envelope reforms). Result: 2 identical diploid cells. vs. Meiosis: 4 haploid cells.
Context turns a cheat sheet from a lookup table into a decision-making tool.
Step 6: Test Your Cheat Sheet Before the Exam
Take a practice exam with your cheat sheet. This reveals two things:
- Topics you included but couldn't find fast enough (reorganize them)
- Topics you left out that you actually needed (add them)
Revise your sheet after each practice test.
Digital vs. Handwritten: Which Is Better?
The research on handwritten versus typed notes is mixed. The practical point is simple: you can't write as fast as you type, so handwriting pushes you to summarize rather than transcribe. Typing works too, as long as you rewrite instead of pasting.
Handwritten cheat sheets are better when:
- Your professor requires handwritten sheets
- You want the cognitive benefits of slow, deliberate writing
- You're making a one-page sheet for a specific exam
Digital cheat sheets are better when:
- You need to revise and iterate quickly
- You're building a reference that grows over the semester
- You want to include diagrams, tables, or formatted equations
- You plan to share with study groups
- You're preparing for a comprehensive final covering months of material
Tools can speed up the digital approach. Scholarly's cheat sheet maker drafts a sheet from your study notes or uploaded PDFs, and the free formula sheet generator drafts formulas from a subject and topics you type, with no account. Start them after your from-memory pass, so you still do the recall yourself, and check the output against your course.
Cheat Sheet Strategies by Subject
STEM Courses (Physics, Chemistry, Engineering, Math)
Focus on formulas and their conditions of use. Include:
- Fundamental equations with variable definitions
- Unit conversions you always forget
- Common problem-solving procedures (steps for specific problem types)
- Key constants (gravitational constant, Avogadro's number, etc.)
- Boundary conditions and when equations break down
Pro tip: If your course involves calculus, include common derivatives and integrals you haven't memorized. These save significant time on exams.
Biology and Pre-Med
Biology cheat sheets benefit heavily from comparison tables and process flows.
- Side-by-side comparisons (mitosis vs. meiosis, DNA vs. RNA, sympathetic vs. parasympathetic)
- Metabolic pathway summaries (glycolysis → Krebs → ETC with key inputs/outputs)
- Classification hierarchies
- Enzyme names and their functions
Standardized exams usually don't allow your own notes (the AAMC prohibits them on the MCAT, for example), so use your sheet as a study tool and pair it with AI-generated quizzes to test whether you actually know the material or just recognize it on the page.
Social Sciences (Psychology, Sociology, Economics)
These courses test concepts and their applications more than formulas.
- Key theories with their creators and core claims
- Vocabulary definitions in your own words
- Real-world examples for abstract concepts
- Contrasts between competing theories
- Experimental findings and what they demonstrated
Law and Business
Focus on frameworks and decision processes.
- Legal tests and their elements (e.g., the four elements of negligence)
- Decision frameworks (SWOT, Porter's Five Forces)
- Case names with their key holdings
- Statutory definitions
- Flowcharts for analytical processes
Common Cheat Sheet Mistakes
Mistake 1: Copying Everything
If your cheat sheet looks like a miniaturized version of your textbook, you haven't made a cheat sheet - you've made a photocopy. The point is selectivity. The process of choosing what to include forces you to evaluate what's important.
Mistake 2: Making It Once and Never Revising
Your first draft cheat sheet reflects what you think is important. After a practice exam, you'll discover what's actually important. Always revise.
Mistake 3: Not Using It to Study
Some students make a cheat sheet and then never look at it until the exam. Use it actively:
- Cover a section and try to recall what's there
- Quiz yourself on the formulas
- Explain each entry to a study partner
This combines cheat sheet creation with spaced repetition - reviewing the material at intervals to strengthen memory.
Mistake 4: Too Much Detail on Things You Already Know
Exam anxiety makes you want to include everything "just in case." Resist this. Every line spent on material you already know is a line stolen from material you actually need help with.
Mistake 5: No Organizational System
Under exam time pressure, you need to find information in seconds. If your cheat sheet has no clear sections, headers, or visual hierarchy, you'll waste precious minutes searching for the right formula while the clock runs down.
How to Build a Cheat Sheet When You Can't Use One on the Exam
Even when professors don't allow cheat sheets, the process can still be useful study if you recall first and test yourself afterward. Here's how to adapt it:
- Build the cheat sheet anyway. Go through all the steps above.
- Memorize it in sections. Use the cheat sheet as a study guide. Cover a section, recall it, check yourself.
- Brain dump at the start of the exam, if the rules allow it. When you sit down, write what you remember from your cheat sheet on scratch paper. This gives you a "recreated" reference sheet for the rest of the exam.
- Convert key items to flashcards. Take the hardest entries from your cheat sheet and turn them into flashcards for spaced repetition practice. Tools like Scholarly can convert your notes into flashcards, saving you the manual work.
This approach keeps the prioritizing work of making a sheet and adds regular retrieval practice.
Using AI to Build Better Cheat Sheets
AI tools have changed how students create study materials. Instead of starting from scratch, you can use AI to generate a first draft and then refine it.
Here's a practical workflow:
- Upload your course materials. Feed your lecture PDFs, slides, or notes into an AI study tool.
- Generate a draft. Use the cheat sheet maker to pull the key equations and concepts from your files. On Scholarly's free plan that is one AI creation and one upload for life (8 MB, first 32 PDF pages), and downloading the sheet needs a paid plan.
- Edit ruthlessly. Remove anything you already know. Add context and conditions of use. Reorganize by exam topic rather than chapter order.
- Test yourself. Use the cheat sheet alongside AI-generated practice quizzes to verify you actually understand the material.
- Iterate. Revise your sheet after each practice session based on what you got wrong.
The AI handles the tedious extraction work. You handle the critical thinking: deciding what matters, how to organize it, and what context to add. That's where the learning happens.

The Bottom Line
A cheat sheet works best as a backup, not a crutch. Research doesn't promise that having one raises your score, so make the process do the work: recall first, prioritize, and test yourself.
Start with what you don't know. Organize by how you'll be tested. Add context, not just content. Revise after practice tests. If you want to save time on the first draft, use the cheat sheet maker for your own notes or the formula sheet generator for a subject and topic list, and then refine the result yourself.
