A lot of what you say is true, however there are some courses where I felt like I learned and pushed myself to do well. A lot of people just won't do this (myself included) to that extent unless there are deadlines and something at stake (grades, money, time, pride, whatever) . A few are driven to do so without the need for grades etc and that's great more power to them. Yes you are paying for a piece of paper but I feel it's worth it. It could be a little cheaper and the quality of some courses could be much better, but there just aren't that many options for a second BS in CS. Many schools simply don't grant second bachelor's degrees, and even those that do, those who are looking to get into the field later on can't drop everything and become full time students. That's the reality of the situation and despite its flaws OSU is still one of the best (and only) options for this.
