The most valuable thing you will take from Neumont is the connections you make with other people while attending there. The quality of instruction is average (probably better than traditional universities although I have no frame of reference to compare against), however the instructors can be somewhat removed from real world development and may not necessarily have knowledge of the most current and up to date techniques being used in the industry. Things have changed immensely since I graduated, none of the coding content I learned in any course work has much relevance any more, although it did serve as a building block to start from. That being said, if you are looking for an environment that will immerse you in the software development world exclusively and skim over all general education and other concerns to help you receive a degree and ultimately a job then you will probably still find those things from Neumont.
No, The high tuition is no joke, most people will spend the rest of their lives trying to pay it off. Even hitting it pretty hard with out many extra expenses it has taken me over 5 years and I still have about a year to go before I will be in the clear.
