I finished SSIC 1-10 this morning. I did each lesson twice before moving to the next. I think it's a great little introduction, and now got me more excited on doing that other KDL online course. The one I have zero time for? Yep, that one. Which writing system should I use? I think KK is more widely used, right? And the 1st gen KDL course might be KK, so at least I'll have consistency with the two courses.
I did find some weird mistakes/inconsistencies in SSIC, but I can't really complain for a free course. It was funny that around Lesson 6 he started referring to them as "Challenges" rather than "Lessons." There were a few constructions they never gave you up front and so you wouldn't know how to construct the sentence at first listen. Finally, pronunciation was erratic in some places (ninzu raiz thym / ninzus raiz thym) or (me rabea / me rabu) are the ones that come to mind immediately. I guess as a resurrected language it's not going to be super solid? Either way, I'm pleased with the introduction and ready to move on. Hopefully they come out with a Level 2 sometime soon.
