lol, modules as in what you study at uni??
In the part time route you do 4 modules -
> Law and Health & Safety
> Construction Technology, Measurement & Costs
> Architectural Science and Building Engineering Services
> Practice in the workplace
You will only generally use Construction Technology, Measurement & Costs in your actual job, however law comes into your work when you do things like contracts etc..
Practice in the workplace is something only part time people do, and is basically a self-made portfolio of the industry, ie what is an architect? what is a structural engineer? etc..
The work is as easy as you make it, but like I say you have to have an interest in buildings
