Evening MBAs can earn a maximum of nine units. When you return, you will work with the exchange coordinator and your program director to find the Haas courses which most closely correspond to those you took while abroad, up to the maximum allowable number of units. You cannot mix and match. The agreed upon Haas classes and grades will eventually appear on your Berkeley transcript, with a note indicating the course work was done while on exchange at the specific partner school you attended. You must make, and pay for, your own travel arrangements.
Some schools have student housing that they make available to exchange students, at varying cost.
In others, you will have to find local housing on your own. Trading housing with visiting exchange students coming to Haas is often an option. The plan does not cover emergency medical airlifting or repatriation of remains. Further, you would need to pay out of pocket for any health expenses incurred while on your semester abroad, and seek reimbursement after you returned. The partner school will provide the documents needed, but you are responsible for submitting them to the appropriate governmental agencies far enough in advance that you can start school on time.
