Quant progress (early stages)

I am doing the 2 month study plan, and I did the mega practice: all previous concepts from day 6, and I did reasonably well– not awful, but lots of room for improvement. I went to do some more testing, so I did the arithmetic quiz 1 and 2 that are listed as optional under day 6, and was left feeling so so so defeated. Are these two quizzes intentionally so much harder than the mega practice? I really did so much poorer on those two in comparison to the mega practice that it was really jarring and disheartening. Any advice?

slow down, use chat gpt to explain things / generate more practice questions, study for the quizzes before you take them. Some quiz questions are quite hard - using the 5-lb arithmetic as another way to measure progress is helpful.
