I also am wondering about the same question that @ucbalumnus asked above: Why do you want to transfer?
Generally to transfer to an Ivy League university (or other top ranked university) you need a good academic reason. I do not understand what it would be in this case.
Years ago I got to participate in a computer science seminar at WUSTL. I was impressed with the students in the seminar and the professor leading the seminar, and had a great visit.
If I understand your question you have not even started yet at WUSTL. It is a very good university with a strong CS program. My suggestion is that you congratulate yourself on getting accepted to a very good university, and that you go there intending to make a strong effort to stay ahead in your classes and to do well. Remember that software can take longer to debug than you might expect. This is only one of several reasons why staying ahead in your work will help you out.
