Agreed, well put. I also found that as I became more familiar with my growing vocabulary, I tended to anticipate words. I finished the current tree 2 weeks back, and am now reviewing as much as I can. Eagerly awaiting 2.0! I may just close out and start from Intro to repeat the whole tree.
I admit that her pronunciation is quite different from others on here, but I like that it's a challenge for me to understand a variety of native speakers. It reminds me of how my accent in English might be difficult for L2 English learners to understand compared to what they might hear in a course.
For me, it's a good test of my progress if I can figure out what she's saying.
