<p>Getting back to your original question, you don’t need to worry for slipping down to Bs in a few classes, but don’t freak out if you have to write a letter. My son, had a couple of Bs and a B- his spring semester of senior year due to being gone at various competitions and a wee bit of senioritis. They sent a letter saying he was not at risk of losing his acceptance, but as it was quite a change from his prior record, they wanted him to explain the drop. Not a big deal, but just be prepared that you mihgt see that and don’t worry about it.</p>
<p>I also agree about not jumping ahead too far. If you place out of classes, then the more advanced classes are not pass/fail first semester.</p>
