@Januaryxo313 Well you should have completed the major req first. The gen ed does not have to be completed before transfer. Yes you must complete all as they are required, plus there is one strongly recommended which you should also do to be competitive. That’s 18 courses. You have until the spring before UC fall enrollment to complete, so you do not need them all completed when you apply in fall.
Also AA degree is not needed at all. Drop it. Just focus in UCLA major req.
Lastly, your GPA will likely not get you into such a highly competitive major. These required courses are not a piece of cake. Off the top of my head, i believe these engineering majors have about a 3.8 average transfer GPA.
