#feedback captions are not working on this video! i would really appreciate captions added or a transcript be made available. thanks!

#help - I went from getting almost every question wrong in the first half of this unit, to now breezing through the last five questions no problem, correct and on target. what does that say about me? the first half of these questions were casual logic and assumption gaps, right? should go back and relearn that material? advice please!

Out of the 13 "You Try's" for this unit, I have gotten 3 correct. I am at such a loss right now. This is the first unit I have struggled with so far in 7sage and it just will. not. click.

I am reviewing every mistake, I've watched every video, I've walked away and taken breaks, and I just don't know what to do anymore!

I guess I will just have to come back to this unit later.
