How to Memorize Definitions for an Exam
If you're figuring out how to memorize definitions for an exam, don't start by repeating them word for word. First make sure you understand each definition, then pick the two or three key words that carry the meaning, turn it into a flashcard you can quiz in both directions, and finally write it out from memory. Understanding plus key words gets you most of the way; recall practice does the rest.
If you've got a glossary of 60 terms and no idea which ones you actually know, FlashDeck turns them into one card per definition and shows you only the ones due today: Build my study plan.
Understand before memorizing
Trying to memorize a definition you don't understand is like memorizing a phone number in a language you don't speak. You can do it, but it's slow and it falls apart the moment the question is worded differently.
The explain-it check
For each term, cover the definition and try to explain it like you're telling a friend in eighth grade. Use your own words. If you can't, you don't need memory tricks yet. You need to reread that section, ask your teacher, or look at an example.
Attach an example
Every definition gets one concrete example.
- Operant conditioning (psychology): learning where behavior is shaped by its consequences. Example: you study more after getting praised for a good grade.
- Osmosis (biology): the movement of water across a semipermeable membrane. Example: a raisin swelling in water.
- Opportunity cost (economics): the value of the next best option you give up. Example: the shift you didn't work because you went to the game.
Examples are what let you answer applied questions ("Which of these is an example of...?"), which many exams love.
The key-word method
Most textbook definitions have a few words doing the real work and a lot of filler. Find the load-bearing words and memorize those.
Step by step
- Read the full definition.
- Underline two to four key words. For osmosis: water, across, semipermeable membrane.
- Say the definition using only those key words plus your own glue words.
- Check it against the book. Did you keep the meaning? Then you're done.
Key-word examples
| Term | Full definition (textbook-style) | Key words |
|---|---|---|
| Osmosis | Movement of water across a semipermeable membrane | water, across, semipermeable membrane |
| Opportunity cost | Value of the next best alternative given up when making a choice | next best, given up |
| Photosynthesis | Process plants use to convert light energy into chemical energy stored in sugar | light energy, chemical energy, sugar |
| Primary source | A document or object created at the time being studied | created at the time |
When you need it word for word
Some teachers or courses want exact definitions. In that case, use the key words as a skeleton, then learn the full sentence in chunks: first half, then second half, then both together. Check every word each time. For long lists, how to memorize 100 vocab words in one night has a batch approach that works for glossaries too.
Cards both ways
A lot of students make definition cards only one way: term on the front, definition on the back. That's half the job.
Term to definition
See opportunity cost, say the definition using your key words. This is what short-answer and "define" questions test.
Definition to term
See "value of the next best option you give up," say opportunity cost. This is what multiple-choice and matching questions test, and it's often trickier because similar terms compete.
Tell-apart cards
For terms that get confused, make a card that asks for the difference.
- Mitosis vs meiosis?
- Classical vs operant conditioning?
- Weather vs climate?
These cards are small, but they catch a lot of trick questions.
Here's the problem with doing all this by hand: you end up with three cards per term, 150 cards total, and every night you're flipping through all of them, including the 100 you already know cold.
Here's where FlashDeck helps: paste your glossary or study guide, or upload your slides as a PDF, and FlashDeck writes one card per definition using only what you pasted. You can delete any card. Each day it shows only what's due: Knew it sends a card out to a day, then three days, then a week; Missed it brings it back tomorrow. So you spend your time on the definitions you're actually shaky on. Build my study plan
Write it from memory
Flashcards are great for quick recall. But on many exams you have to write the definition out, and that's a different skill. Practice it directly.
The blank-page test
- Take a blank sheet.
- Write down 10 terms from your list, no peeking.
- Next to each, write the definition from memory.
- Check with a different color pen. Circle any missing key words.
- The circled terms become your focus for tomorrow.
Make it harder over time
- First pass: term given, write the definition.
- Second pass: definition given, write the term.
- Third pass: write a sentence using the term correctly in context.
That third pass is gold for essay and free-response questions, where you have to use terms, not just define them.
A daily routine for definitions
- 5 to 10 minutes of flashcards on what's due
- 5 minutes of one blank-page test
- One tell-apart card for the pair you confused today
The same approach works for vocabulary in any class. See the best way to study for a vocab test for a three-day version, and how to make flashcards for medical terminology if your definitions are full of Greek and Latin word parts.
Get your glossary into cards in about a minute
Paste the terms and definitions from your study guide and FlashDeck writes one card per definition, using only what you pasted, so the wording matches your class. From tomorrow, you'll review just the definitions that are due, about 10 minutes a day.
FAQ
What is the best way to memorize terms and definitions?
Make sure you understand each definition first, then pick its key words and quiz yourself with flashcards in both directions. Add an example for each term. Finish by writing definitions from memory on a blank page.
How do I memorize definitions fast for a test tomorrow?
Focus on key words instead of full sentences, quiz yourself in small batches of about 10 terms, and repeat only the ones you miss. Do a blank-page test at the end. Then sleep and do one quick review in the morning.
How do you memorize definitions word for word?
Use the key words as a skeleton, then learn the full definition in two or three chunks. Say each chunk from memory and check every word. Put the exact definition on the back of a card and practice until you can write it without errors.
Any tips to memorizing a lot of information for a test?
Start early, study in short daily sessions, and quiz yourself instead of rereading. Break the material into small groups and review older groups before adding new ones. Spread practice over several days if you can.
Why do I forget definitions right after the exam?
Information you learn once and don't revisit tends to fade quickly. If you'll need the terms again, like for a final, keep reviewing them with longer gaps between sessions. A few minutes a day keeps older terms from slipping.
