I have transferred once and it is pretty easy. Number one thing to remember is, get good grades at your first college and you will be accepted almost anywhere. If you look at a prospective college's website, just go to prospective students section, then to transfer students. It will tell you what you need to know there.
Another thing to consider, finish your general education requirements at the first school you attend. When you transfer to a different school, more than likely they will not make you take their gen-ed classes, even though they may have different requirements than your previous school. Hope this helps.
