Basically, the attrition rate is 32% over the past five years as stated in their student manual. 2.0 is the grade required to pass. If you get below 2.0 for each two semesters averaged, then you are dismissed. Most people leave of their volition rather then getting dismissed. Oh yeah, if you get below a 2.0 in your first semester, then you're out too.
Faculties are nice if you approach them and will try to make you understand the material, but they don't care very much if you pass or fail the course. People in the registrar are VERY mean except for the associate dean, who is the most helpful guy. Many people have the same thought as me. There are even people claiming that some professors are deliberately making the students failing out. However, the admissions office is very nice and ironically, they are the ones who solved a few of my issues, lol.
Everything I said in the second paragraph is based on my opinions. You might find people there to be much better or worse than how I feel.
