Course Challenges
Prerequisites? Math11 …Really, no experience required!
Aptitude? Most people can learn basic programming
Interest? CS is creative and rewarding, but it can also be time-consuming
Time? You can't expect to learn complex skills by listening to lectures This class will probably have the heaviest workload of any of your
classes this term Study habits?
Your brain needs time to learn. Don't try to do all work the night of the due date
You need time to get stuck, ask for help, get unstuck, get stuck again…
