<p>I definitely know how you feel, I'm so glad it's all over for me. But you're really rounding the bend. I found the pressure of senior year to be a different sort, mostly just interminable waiting, which in some ways is better, because it's all out of your hands. I would definitely give ACT a shot, both tests do have a distinct difference. Some people really prefer one over the other. And don't feel too pressured, your 'backup' scores of 730 and 700 are by no means terrible, you can only go up. It's a matter of getting maybe 3 more questions right on the bio test, and you're set!</p>
<p>Things look pretty good, the upward trend in grades compensates for a slow start especially with more difficult courses...maybe consider early action/decision if you really like Dartmouth. GL with your AP scores, and have a fun summer!</p>
