The four year university can be quite expensive. The average cost for a public university per year is about $23,000. The average cost for a private university is around $44,000. So say you do get accepted into a public university, but need to take out student loans. By the way, the interest rate on student loans is ridiculous. It's about 3.5 percent. So that's $22,000 at 3.5 percent times the four years you will spent in college comes to about $100,000!!! And that's just for your undergraduate degree. Also keep in mind that your not only spending money, but you are also spending time. So if you decide to take the university route, be prepared to dedicate 10 years of your life to school. On the other hand, the average cost for trade school is no more than $10,000 and about two years to complete the training program.
