The techniques/skills you learn in ACST101 will be used throughout your AppFin degree. The Elements part of the unit is a very brief summary of the rest of the AppFin degree. There are whole units devoted to most of the topics in Elements. So the Elements component is a bit like a taster plate of the rest of the degree (but it is a very bland, basic plate because its just definitions, etc).
I wouldn't call ACST101 an indicator of the rest of the degree. The rest of the units are obviously more interesting, more difficult, focus on specific areas and will build more on the techniques and elements you learn in ACST101.
