I am registered for both INF206 & INF207, & I can't help but see the two courses as very similar.
It seems to me that INF206 (Systems Analysis & Design) lays the foundation for INF207(Object-Oriented Systems Analysis), so i'm just wondering if it is best for one to 1st go through INF206, before tackling INF207.
Like I said on the other side: Different ways of doing the same thing. The book runs them in parallel. But do them sequentially if you like. As long as you've got the time, it can't hurt. Notice that the due dates for the assignments are concurrent, however. Look at the case study for Assignment 2 for both the courses, and compare. You may find a little surprise there.
