Relax. Now is not the time to be freaking out.
A 30% on exam 1 is already roughly a 24 study score, scaling to around a 26, so you're well on your way to a 25. And, as the study design has been out for a while, they may make the exam slightly harder, in which case 30% may be sufficient for a 25. 60% is almost 10% above the median score. Exam 2 has roughly the same score spread, and is even slightly more lenient in the upper range.
Keep yourself collected in the exam - solving the "easy" questions is likely going to be enough to get you over the line. Be careful with your algebra and show all your working. At least start every question, if you have any vague idea of what they're asking (or even if you don't). You never know what you could get a stray mark on. The first two questions (as in, 1a and 1b) are likely going to be taking the derivative of some function, and that's already 10% of the test, so if you solve those carefully and you're almost a third of the way to a 25. Even if they decide to switch things up a bit and throw a curveball in there, know that the rest of the state is going to be equally as screwed over as you, so it's not going to ruin your chances. Just take it easy and read over your notes for now, you sound prepared enough to get a 25.
