I applied to around 15 Ph.D. programs, out of which I have one official acceptance offer, many rejections, and like 4 unknowns. I don't think any of the other schools will be accepting me since I haven't heard anything from them.
My top choice just rejected me after flying me out for a campus visit (along with 2 other finalists). I was also told by another good school that I was on the waiting list, but the people higher up on the list had already accepted so they couldn't offer me a position.
I'm worried that I'm settling for the only offer I've gotten (at a virtually non-ranked program in Stillwater, OK) and I could have a better chance of getting in to a much better program next year if I improve my GMAT scores and get more research experience - which would help my prospects once I'm on the job market as well.
However, there are many costs associated with waiting, and I'm not guaranteed anything next year either.
Does anyone have experience with this kind of situation? This is an extremely difficult decision for me and I could use any information/suggestions that anyone has!
