Be careful with that. My school (Art Institute of NYC) was only supposed to take me 18 months to finish. But what they dont tell you when you register is that you literally have to take 5 or more (mind you they are 4 hrs long each) classes each quarter in order to finish in that time slot. Semesters are usually shorter in schools like that as well. You are basically given the same amount of work or more in a shorter period of time. Sounds great to finish in only a few weeks or whatever but they will be insanely hard weeks. And if you have trouble studying and stuff that may not be the best option for you. Besides I really dont think most people learn much in an intensive program like that because you are just bombarded with info. Most of it will not stick with you. And if you are going into a professional environment straight out of school, and you havent learned what you were supposed to, it can end in disaster.
Just my 2 cents.
