A-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. At GCSE the grade comes entirely from exams, and Pearson Edexcel and Eduqas test programming in an on-screen exam where AQA and OCR use paper; every A level includes a programming project worth 20 per cent. For A-level, the algorithmic complexity and recursion content is where tutors with degree-level CS background tend to add the most.
