If you want to practice in Iowa, then go to Drake. Otherwise, for everything else, St. Thomas Law is the better option for quality of education. I have seen a few students from St.Thomas law and can say, they seem like veteran lawyers. That is more-so exaggerations on my part, but the St.Thomas Law graduates do have a sense of professionalism, seriousness, and drive you do not see in many graduates. William Mitchell graduates are somewhat the same as well. I have never met a Hamline Law graduate yet, but once I do, I will tell you about it.
For job market, Minnesota is a good place to practice if you are used to the bone chilling winters. William graduates tend to hold down more jobs in the Minnesota market though due to the bigger companies partners and recruiting officers having gone to Mitchel. However, St.Thomas graduates are employed in various legal offices in the Minnesota market as well. Some even venture off to start their own pracitces or practice law in a different state.
You can get into St. Thomas though with your scores. GPA is, I think, 3.5 for the 75% and 3.02 for the 25%, and the LSAT is 159 for sure.
