Hi,
My intended major is Computer Science. I got in as undecided at UCI and in pre-sciences at UW Seattle.
I’m super-confused between the two. The tuition fees are the same for me.
For me:-
pros at UCI are great location, California (I’m in love with this place, literally), weather, comparatively easier to get Computer Science major.
cons at UCI are majority of asians (no diversity), it is a commuter campus so it probably tends to get pretty boring (or so I’ve heard).
pros at UW are Seattle in itself is a great city, top 10 ranked CS program, great campus, awesome athletics and school spirit
cons at UW are weather, very hard to get into the CS program due to competition.
Please provide more insight and help me make a decision. Thanks a ton in advance 
How hard is it to transfer into CS at either school. I have heard that CS at UWS is very difficult to gain access to.
Where do you see yourself establishing a life? California or Seattle? I think that should be the biggest factor if finances are the same.
Regarding UW, a recent article in the Seattle Times reported:
"Although computer science and engineering is a tough program to get into, the picture is getting better. In 2016, 43 percent of bachelor’s applicants were admitted to the program. In previous years, the admission rate was lower.
“[The CSE Department] is now enrolling about 370 new undergraduate students each year, double the number it was able to accommodate in 2012… This year, it is asking for $6 million from the Legislature to increase the number of students it graduates by 120 degrees per year. Most of that increase would be in bachelors degrees, Lazowska said.”
According to the ASEE profile, UW engineering and CS appear to enroll a broad range of students (middle 50% range SAT 1170-1420; ACT 27-33). Knowing that you will need to be somewhere around the top 40 to 45% of applicants for regular admission to the CS major, you might get a rough estimate of your prospects by considering where you stand academically in relation to the entering class. Although your personal work ethic may be the most important factor for determining success, I think you would want to be toward the upper range of these scores.
