I know nothing about Western State never even visited the campus, but if you can't handle the pressure of a law school exam then your really going to struggle with the bar. I know attrition sounds bad, but having gone through the bar personally I can tell you 1L exams are an absolute cakewalk compared to the bar.
I don't imagine Western State requires people to get kicked out as that would make no sense if they think you are capable of passing the bar and you are paying them they will want you to succeed. However, if it does not appear you can handle 1L your much better of leaving then opposed to spending another two years of your life and 80,000 dollars to fail the bar. A J.D.without a license to practice law is really not that helpful in the real world.
I am not saying Western State is some pinnacle to legal education, but plenty of people attended Western State and are doing very well the head District Attorney of San Francisco is a Western State Grad, Head District Attorney of San Diego Western State Grad,

I worked on a few cases in orange county and many of the city attorneys were Western State Grads and many were quite good. Bottom line is if you pass the bar from any school you are a lawyer it is extremly difficult to do though and realistically if you cannot handle 1L exams the bar is going to be literally impossible and your much better off getting out while your ahead.
Again I don't think Western State is some phenomenal school, but can get you a bar exam ticket and if you get a law license it is up to you to succeed with it. Sure going to Harvard will open more doors and attending Western State may close the door to becoming a Supreme Court Clerk, but not many people get those jobs anyways.
Just my two cents about the school having never been there, but I think that Western, Cooley, and many other schools get an unfair rap. If you think a law school exam is difficult when you are told exactly what the subject will be try balancing thirteen different ones for 3 days straight i.e. the California Bar Exam. Once you get into practice that isn't that tough either representing a client, getting objected to, being on time deadlines, etc is far more strenuous than the bar. The end of my rant mercifully : ) and anyone that attends Western State good luck!
