This was how I felt the first week, happy, understanding, getting 100% and I even got bonus problems correct. Of course that's when we were reviewing past stuff. I had to work at remembering correct terms and vocabulary but the math made sense to me, for the most part.
Almost right away, I started having dreams with numbers and algebraic equations and symbols. They'd just sit off to the side of the main storyline of my dream. In the morning, I'd just chuckle that I was doing so much math, so quickly, and ALL the time, that I was even dreaming about it.
Then the numbers stated taking over, when I was asleep AND when I was awake.

And they started getting spooky.
And now, with my final exam (worth 30% of my grade) coming up, I'm having outright nightmares, and all the formulas and vocabulary and symbols are a huge tangled mess in my head!
Wish me luck, and sleep, and getting the kids to cooperate so I can get there on time, and to be relaxed so I can remember what I need to. He's letting us have a page of notes, YEAH!!!!, so I can at least write out the formulas and Michael has let me borrow his calculator and has helped me a lot.
