I have posted the exercise sheet for Tutorial 7 on the course web page and NB. As usual, the questions themselves are followed by some examples and solutions, based this time on questions in past exam papers.
These tutorial exercises are running concurrently with the Inf1-DA assignment. Consequently, the tutorial meetings next week will also be a chance for you to discuss the assignment with your tutor, ask questions, and seek help. Please do use this opportunity: start work on the assignment well before the tutorial, take along your work, and tell your tutor which parts you find difficult.
