Generally speaking, any Associate's Degree will count as roughly half the credits towards any Bachelor's degree. However, not all your classes might transfer equally. If you're going into a BSN program without holding an Assoc. in Nursing and the RN license, you will need to be sure that you have completed all the BSN program's prerequisite courses, which will almost always include general biology, general chemistry, anatomy & physiology, and perhaps microbiology and nutrition and developmental psychology. Each school has their own unique requirements, but they are usually very similar. So contact UCLA to see what courses they require and have them examine your transcripts to see what counts and what doesn't. If you don't need many prerequisites and can enroll in the BSN program right away, you will be done in roughly 2 years. If you have many prereqs to take and not many of your courses transfer, then you might need more like 3 years.
