I understand that you are a sophomore now and plan to transfer to another school in next spring as a junior. For your question, yes, there would be some schools that can receive you for spring semester. Second, I would not suggest you to take this path except you are in any emergency situation. If you stay one more semester as a junior, then you are applying to colleges. Transferring as a junior in the middle of year would not look good to colleges either, and you are going into a different school which might have different culture, attitude, grading system, new friends and all other new stuff. That requires a serious adjustment process. Even any good student would take some time to adjust and this adjustment would take some of your very precious energy that is supposed to be spent on your preparation for colleges in your junior year. My recommendation is rather to select a good college counselor and work hard for your college application options while you are staying at the current school. This can give you a better chance for you to go to a better college later.
