First of all, great you want to enter the teaching/education world! We need more teachers. Now to your question, there are several universities and colleges that are promoting a "fast track" approach to graduting before 4 years. However, this might require you taking summer school courses as well as winter classes. However, if you ask me, those were my favorite times to take classes as it seemed more straightforward without the "fluff". But you will need to also pass state required exams to teach. Each state has different standards so make sure you look into the state department of education to see what their requirements are. Best of luck!
