Reminder: Colour codes

The exercise pages are colour coded:

Green

These exercises are, generally speaking, straight-forward applications of the theory explained in the lecture.

Green are the must-do tasks to gain a fair understanding of the material, pass the module, and earn an average grade.

Orange

These are designed to improve your understanding of the technical parts, and will push your skills to a higher level.

Orange is at the level of upper-second/first class.

Red/Blue

Red and blue designated advanced or optional exercises, and are not examinable -- they are there only to encourage you advance and deepen your understanding.

This is for those of you who want to test their skills and enjoy challenge.
