How it works

How to revise with these GCSE flashcards

Pick a subject and topic. Choose one topic to focus on, or All topics to mix them up. Foundation students can untick Higher tier, and Combined Science students can untick Triple science.
Test yourself on each card. Read the question and say or write your answer before you turn the card over. Recalling it from memory is what makes it stick.
Be honest about how it went. Tap Again, Hard, Good or Easy, the same four buttons Anki uses (or swipe right if you knew it and left if you didn’t, like Quizlet). Cards you got wrong come back later in the same session; cards you knew come back after a few days, then a week, then longer.
Come back each day. The bar shows how many cards in your topic you know well. A little every day beats one long session the night before.
Check yourself with a quiz. Ten multiple-choice questions with the answer explained, and a link so a friend can take the same quiz.

Four ways to revise

Flashcards. Flip and mark each card; smart repeat works out what you need to see again and when.
Quiz. Ten questions from your topic with four answers each, your score, and every missed card explained.
Daily 10. Ten questions a day for each subject, the same for everyone. Keep your streak going and share your score.
My cards. Type your own questions and answers into blank cards, then revise them with smart repeat or a quiz. They’re saved on your device, and you can save a copy to move them.

What’s covered

Cell biology

What is the function of the nucleus?: Contains genetic material that controls the activities of the cell
Why does a sperm cell contain many mitochondria?: To release energy for the tail to swim to the egg
Give an example of active transport in plants.: Root hair cells absorbing mineral ions from the soil

Organisation

What is the order of organisation in a living organism, from smallest to largest?: Cells → tissues → organs → organ systems → organism
In the practical on pH and amylase, how do you know the starch has all been digested?: Iodine in the spotting tile no longer turns blue-black
