OCR GCSE Computer Science

OCR GCSE Computer Science (J277)


Like all sciences, the goal is to learn how things work! In physics you will learn how the universe works, biology will teach you how the cells of every living being do their job. Computer science is exactly the same, instead this time you will be looking at the future!

Computer science explores what computers are made from, how all the different pieces of the computer work together. How we connect them into networks which span across the entire planet allowing us to share everything from important data to the latest memes! Let’s not forget the programming.

  • Programs that will be learnt

    Can’t Guess This

    • A program which generates a strong password.

    Dice Game

    • Two player game, each player rolls up to six dice.
    • To roll their next dice the two previous numbers must be sequential, any number out of sequence ends the round.
