What’s the difference between Courses 1-3 and Levels 1-3?
I came back to SSiW after a long gap and have found myself doing Level 1, whereas before I was doing Course 1. I think I need to go back to doing Course 1. I think I’d only done about 6 or 7 lessons; should I start at the beginning again?
The courses are the older material, while the levels are the newer material. Personally, I reckon that the newer material is better, but it’s worth doing both, starting with the newer stuff.
