<p>What did you get your B’s in? If they are not math/science classes I wouldn’t worry too much. The best advice to ease your mind is to call or e-mail admissions and ask them. They will see your grades eventually. Better yet, you still have a couple of months to try to improve on those grades.</p>
<p>Try to keep your grades up, nevertheless, I wouldn’t worry too much if those subjects arent ‘core’ courses that Caltech puts a lot of weight on… you’d have to be someone very capable to get into Caltech, so keeping your grades up wont be a problem :)</p>
