I think you most certainly can. I'm part of the mentoring program - you should look into it, pm me if you want more info - here at cal and a lot of my fellow mentors are business majors.
You should look at the Haas webiste for transfers (Admissions for Transfer Students, Undergraduate Program - Haas School of Business, UC Berkeley
) Please note that getting into Haas is difficult, but not impossible. I hope you are doing your best and taking all the required courses.
For the future, you should refer to the UC Transfer forum; they will be able to assist you further and will generally be more helpful. Good luck.
