AS-level Computer Science tutors

Computer Science in the UK covers algorithms, data structures, computational thinking, programming (usually Python at GCSE, Python or Java at A-level), and theory — networks, architecture, databases, ethics. Tutoring most often unsticks two things: the move from 'I can code' to 'I can write pseudocode and trace algorithms on paper under exam conditions', and the theory papers, which reward precise definitions over intuition. AQA, OCR and Eduqas differ on programming language and on the NEA project. For A-level, the algorithmic complexity and recursion content is where tutors with degree-level CS background tend to add the most.
