Transfer from Tufts Engineering to A&S?

I recently got accepted into the School of Engineering at Tufts, and I am thinking about switching to major in Biology at A&S. Is switching a difficult process, especially to a different school? It is still very early on, will it be easier for me if I take steps to switch now? How? Do I have to completely re-apply?

Its easy to switch in and out of things, no worries. You can think about it over the summer and switch in the Fall or after your first few semesters.
