This is a very easy subject and the workbooks allow for a way to follow exactly what happens in class as the lecturer will simply be going through the book in lectures. As well as this, the workbooks also provide tutorial questions in the back which are used for tutorial sessions; again a very easy way to understand what is going on in the subject.

This subject is not very difficult as it seems. It is just the way it is being taught makes students think that way especially if it is offered in mixed mode.
