2 year study options

[Jotadas]

I want to apply for a temporary study visa. But the initial program I selected is for 12 months. If I apply for another course for an additional 12 months, after the 2nd year, can I apply for a 3 year work permit?
Or do I have to select a 2 year plan from the begining?
