CSULA vs CSUF vs UCD, UCSD and CSULB Waitlisted

As the title says I fortunately got accepted into CSULA and CSUF as a psychology major and got into UCD as a philosophy major. I just wanted to know how classes (and mostly how campuses are in general) are like especially since I want to get into pre med ^^ and which one seems best since as I do want to go down to SoCal, my parents want me to stay in UCD since it’s considered a “good school” to them compared to CSUs.
Also wanted to ask what the chances of getting off the waitlist for UCSD or CSULB since CSULB was one of my dream schools.

Out of the 3 accepted schools, UC Davis is by far above and beyond the rest in academics, research and internship opportunities.

As a possible Pre-Med student, you want to attend a school where you have the best chance for a High GPA, Good Pre-Med advising and access to Medically related EC’s. Also you want to keep costs at a minimum since Medical school is very expensive.

What are cost differences between the schools?

Academically, UC Davis would the most challenging but having a top 10 Medical school nearby would be an advantage.

For UCSD waitlist 2019:
Waitlist Offers: 20,000
Waitlist Admits: 4,300

No waitlist data for CSULB 2019.

I would focus on the schools that have accepted you.

thank you! and would it be possible if i did my undergrad in UC Davis as a philosophy with a pre med emphasis and for med school/grad school seem possible to be admitted to somewhere like UCLA/UCI/USC?
