How many quarter units do you have? Be very careful and try to meet these requirements BEFORE reaching 120 units and you’re guaranteed a change of major.
2.0 Cumm GPA &
2.0 average GPA or above in ICS/CSE 21 and 22 or Informatics 41 and 42, or ICS 31 and 32; and one of the following: Math 2A, Math 2B, ICS 6B/Math 6B or ICS 6D/Math 6D.
as long as you do that before hitting 120 units and can fit everything else in the curriculum into graduating on time (I think 9 quarters for transfer?) you should be accepted.
