Welcome to College Confidential. Sorry about your home situation and it should be addressed in one of your personal insight essays. You do have good HS course rigor but top schools like UCLA expect you challenge yourself and also get good grades. If your UW GPA is 3.37, your capped weighted would be around 3.6-3.7, which is well below the 25th percentile. UC’s tend to be very GPA focused so this will definitely impact your chances. You have a solid ACT and some good EC’s but these will not overcome your low GPA.

Having CA residency will help with tuition costs and give you only a slight advantage based on acceptance rates. Below is more UC statistical data and I suggest you expand your college list and consider UCLA a High Reach.
