What is computational thinking a level?
Computational thinking is a process of problem-solving. This can involve: Decomposition — breaking a problem down into smaller parts. Abstraction — removing unnecessary detail to reduce complexity. Pattern recognition — identifying the problem as an example of a class of problems that have already been solved.
How long is a computer science A level exam?
2 1/2 hours
As previously mentioned, A level Computer science consists of two exam papers, each 2 1/2 hours long and each worth 40%.
What is computer science as level?
In AS and A level Computer Science, students learn the principles of computation and algorithms, computer programming, machine data representation, computer systems (hardware and software), computer organisation and architecture, communications and networking, databases and the consequences of using computing.
Why do computers use the binary number system?
The main reason the binary number system is used in computing is that it is simple. Computers don’t understand language or numbers in the same way that we do. All they really have available to work with are switches and electrical signals, either on or off.
Is coding a computational thinking technique?
Computational thinking is often associated with computers and coding, but it is important to note that it can be taught without a device.
How hard is it to get an A * in A level Computer Science?
A-Level Computer Science is very difficult, with 4.9% of students failing the course (June 2018). This may not sound like a lot, but it is actually one of the highest failing rates of any A-Level. The work in Computer Science is split into two categories: programming, and theory.
WHAT A levels go well with Computer Science?
Computer Science: applicants should ideally offer Maths, Further Maths and Physics. Maths, Further Maths and Computing or Maths, Physics, Computing and AS Further Maths are acceptable alternatives.
