I don't think Olin looked at fall grades. (Some schools don't end their semester until mid January). I supposed they might though for the final cut.
<p>I'm pretty sure that once you arrive at candidate's weekend, the application materials, grades, etc. don't matter any more. I know for sure that admissions does not look at your application again after Candidate's weekend. The interview is the only thing that matters moving forward. </p>
<p>I imagine if you were waitlisted and you sent in better grades in the spring, they would consider that, but I'm not sure. You can always ask admissions any questions you have when you come to candidate's weekend. The people who work Olin admissions are all awesome and really friendly. </p>
