Why a flashcard maker helps before an exam

Cramming the week before a test rarely works, so many students start earlier with a flashcard maker for exams that turns their own lecture material into cards they can review in short sessions.

  • Turn lecture slides and textbook chapters into cards in one upload
  • Keep your own wording so the cards match what your class actually covered
  • Review in short daily sessions that fit around other coursework
  • Export to Anki or CSV on the Plus plan if you already use another app
Example intro biology flashcards for a midterm
MitochondriaOrganelles where most ATP is produced in eukaryotic cells through cellular respiration.
OsmosisMovement of water across a selectively permeable membrane from the side with less solute to the side with more solute.
MitosisNuclear division that produces two genetically identical daughter nuclei.
Enzyme denaturationLoss of the enzyme's 3D shape, usually from high heat or extreme pH, so the active site no longer fits its substrate.
Dominant alleleAn allele whose trait shows up in heterozygotes, masking the recessive allele.

Built from your own material

Upload PDFs, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition, so handwritten-free printed notes work too.

Spaced repetition

Cards you know come back less often and cards you miss come back sooner, so your review time goes to what you are most likely to forget.

Export when you need it

Plus members can export to PDF, DOCX, Anki and CSV. Free users can study every card in the browser.

How it works

Upload your material

Add the slides, chapter PDF or notes you will be tested on. Multiple files can be combined into one set.

Generate your cards

DeckOwl reads the text and turns key terms, definitions and processes into question and answer flashcards.

Review on a schedule

Study in short sessions each day. The spacing system adjusts to what you get right and wrong.

Writing cards by hand takes time that is better spent learning. A generator reads your slides and notes, picks out the terms and ideas your instructor is likely to test, and gives you a deck to edit, trim or add to.

Spaced repetition is the part that does the heavy lifting. Reviewing the same deck over several days beats one long session, and the cards you keep missing get shown more often until they become automatic.

Frequently asked questions

How many flashcards should I make for a midterm in intro biology?

Aim for one card per key term, definition or process from the chapters on the test, which usually means a few dozen for a single unit. Drop any card you can answer in a second or two without thinking, and keep the ones that still slow you down.

How often should I review flashcards before an exam?

Review new cards every day and let older ones come back at longer gaps, since spaced practice tends to beat one long session. In the last few days before the test, run a mixed review of the whole deck.

Can I export my flashcards to Anki?

Yes, Anki export is part of the Plus plan, along with PDF, DOCX and CSV export. The free plan gives you 3 generations per month, and you can study every card in the browser.

Does it work with photos of my notes?

Yes, photos of pages are read with text recognition. PDF, DOCX, PPTX and plain text files also work as input.
