and you can consider transferring to other school after one year, which is quite easy if your GPA for first year is well above average, (say, among top 15% or >>3.5) and you won't lose one penny if you strictly follow the curriculum(because at most schools the courses are not much different for 1st year students).

But for graduate school, the ranking of school and particular department are definitely very important. So you can also consider finishing your undergraduate study at current school, maintaining a relatively high GPA and good performance, and it won't be a problem for you to apply for better graduate schools ------or your job hunting.
