Definitely agree with what the above posters have said. Also, the University of Montana has a median LSAT of 154. 150 is their 25th percentile. To have a really good shot you want your GPA and LSAT to be over the medians.
i have the starter course! my diagnostic was a 154 and i am currently scoring 164-166 ish. taking the june LSAT and hoping to improve by a couple more points in the next month!
