Factors that influence credit transfer:
* University policies: Each university has its own rules regarding transfer credits. Some are very generous, while others are more restrictive. Some might only accept credits from regionally accredited institutions.
* Program requirements: The new degree program will have specific required courses. Only credits from courses that satisfy requirements for the *new* degree are likely to be accepted. A course in, say, Medieval History from your BA might not count toward a Master's in Engineering.
* Grade requirements: Many universities require a minimum grade in the transferred course (e.g., a "C" or better).
* Course equivalency: The university will assess whether your previous courses are equivalent to courses offered in their new program. Even if the course titles are similar, the content might differ enough to prevent transfer.
* Time elapsed: Some universities have limitations on how long ago the credits were earned.
In short: You *should* contact the admissions office of the university and the specific department offering the new degree program you're interested in. They will be able to tell you definitively which, if any, of your previous credits will transfer and how that will affect your overall program length and cost. Don't assume anything; get it in writing.
