Advisors are slow to respond to emails, ya have to contact advisors a week in advance to schedule something, rather than within a week regardless of deadlines. I am a transfer student and i have received a letter saying they have my records however when i sign for classes online it says i need prerequisites i have already taken and so i tried getting a permit but their permit site is down. the registration processs is more confusing than anything and is very fustrating. Also to reach somebody by phone you have to wait absolutely forever before you may get a hold of someone, it is rediculous.
