Taking A Level Computer Science

Two most important questions

Can I study A level computer science if I have not studied it at GCSE?

Many students ask this question. The answer is always ‘yes… but…’. Computer Science requires a lot of programming - it's one of the reasons we insist on a grade 6 in maths or a grade 6 in computer science. If you don’t like programming, you will hate it. There is also quite a bit of complex theory and those who study at GCSE will have a basic understanding of most of it. To be brutally honest, most of the students who have taken computer science after not studying at GCSE have found it a step too far and have not achieved as they would have expected. If you want to be successful, it would be a good idea to prepare a little first, both in terms of programming and theory. 

What can I do to prepare for A level computer science?

The most useful way of preparing would be to improve your skills in programming. Understanding how programming works will help to make everything else in the course make sense. It is also best learnt independently, unlike theory. The programming language we use to create software is C#, with a bit of HTML, CSS and JavaScript for web development. Any work you can do in these would be very beneficial. Below are some links that will be useful:
