F451 and F452 Revision - questions, mark schemes and student sample answers

Database dump from web application revision tool for my AS students. Student answers for some questions maybe missing because database state taken from April.

Formatting might be strange but it should all be in this sequence: 1.Question 2. Mark scheme 3. Selected student answers (high/low level responses). Please note the marks were the result of peer assessment, there is also a 'comments' field for each submission which I've left out because some of the AS kids were a bit silly and included comments in German (some a little rude!)

Level: (Beginner / Intermediate/ Advanced) AS level

Duration: (duration, if applicable) It maybe of some use to anyone teaching Computing at A-level on the OCR board or otherwise.

Teaches: (set of concepts learned) Revision for F451 and F452 exams
