<p>For personal statements, what a Cal admissions rep told me a couple years ago is that personal statements can be a big boost to your app, but don’t bring it down at all if they’re mediocre. It’s just a missed opportunity to boost your app.</p>
<p>That said, you still have enough time to edit them. I would try to edit them and make them stronger if at all possible. Likewise, I would retake the ACT and try to score higher to solidify your chances. If you have to pick only one to improve, go for the ACT because that affects your application more.</p>
