As I see Course(s) they’re somehow more “step by step”. At least at the beginning you learn word by word rather then whole phrases/structures and shortenings come in full only in Course 3. Actually, if I think more closely, Course 1 deals with beginner’s things like words, how to make past and future tense, some mutations are learnt etc. Course 2 deals more with possessives and reflexives (ahhh … my trouble number 1 ) and Course 3 goes with shortenings of all kinds I believe southern version even more then northern (I did south all the way through and did only Level 1 Challenge 25 northern as there was not southern one that time yet).
So, now you know what approximately old course brings to you. Levels you know though … they bring a little of everything and for the record, possessives and reflexives start quite early in the process so do soem shortenings especially creating past tense ones.
Well, if I did some wrong explanation, please feel free to correct me, but that’s what remain in my memory (and didn’t escape it through my brain holes. - hehe)
Oh, @jonathanwilliams, but even if you decide to begin with levels rather then continue with Courses, HEY! don’t miss Lesson 6b - bonus lesson which offers you not only something new to learn but endless fun also. I won’t tell you anything more. Let your curiousity drive you there to do it. (however might be wise to come to either Lesson 6-1 and 6-2 or doing at least 10 or so Challenges first).
