What is a Flashcard?

Flashcards are a simple but powerful study tool used to test your memory and strengthen what you know. Each flashcard has a question, prompt, or key term on one side, and the answer or explanation on the other. They’re designed to help you learn actively, not just read or re-read notes, but practise remembering information.

Flashcards are especially useful for subjects like Computer Science, where there are lots of definitions, processes, commands, and vocabulary to learn. But they work for any subject where you need to remember facts or ideas.

Why Use Flashcards?

Flashcards support active recall – a technique where you train your brain to pull information from memory rather than just recognising it. This strengthens your long-term memory and improves exam performance.

They also work brilliantly with spaced repetition (revisiting flashcards at increasing intervals) and interleaving (mixing different topics together during revision).

What Can You Put on a Flashcard?

Anything you need to remember! For example:

  • A keyword on one side, definition on the other

  • A question on one side, answer on the other

  • A diagram on one side, explanation on the other

  • A piece of code on one side, what it does on the other

In Computer Science, you might create flashcards for:

  • Python syntax

  • Definitions like “Boolean”, “Algorithm”, or “Iteration”

  • Command line functions

  • Key stages of the software development lifecycle

  • Hardware vs. Software components

How to Make Flashcards

You can create flashcards by hand using small cards or paper, or digitally using apps like Anki, Quizlet, or Brainscape. Some students prefer digital cards because they’re easy to organise, colour-code, and use on the go.

Whether digital or paper, make sure:

  • They’re clear and concise

  • You use your own words when possible

  • You don’t overcrowd the card – stick to one idea per card

  • You shuffle and test yourself regularly

The Power of Repetition

Flashcards are most effective when you:

  • Review them frequently

  • Remove cards you’ve mastered

  • Focus on the ones you get wrong

  • Come back to difficult cards later in the week

The more you use them, the more you’ll be amazed at how much you can remember.

Summary

Flashcards are one of the most efficient ways to revise:

  • They’re portable, practical and powerful

  • They support memory through active recall

  • They help you break revision into short, sharp sessions

  • They can be adapted to any subject
