I go to a school comparatively ranked with WUSTL. The transfers here tend to do alright in OCI. I would definitely advise transferring if I were you. Just think if your grades tank after this semester, then you are at a T3 with absolutely nothing going for you. The job search is tough and you should do everything possible to make sure you have the best advantage you have. law review is great, but realistically, its still law review at a T3 (not to knock it at all, but just saying). I cant think for the life of me where you are at right now, but I would venture to say that there are minimal if any decent firms at OCI.
The firm I work at has maybe 2 tier 3 kids (howard) and that is it. Its tough even at the top.
NYC2L is right though, even at WUSTL, you would have to be in the top 30% probably. However, transfer apps just have their grades to go off of from the other school.
