Need help deciding if I should go to UCLA?

I am a transfer student that just got accepted to UCLA. UCLA has been my dream school since forever and I really want to go here. The only problem is that I got accepted as an environmental science major and I really want to study biology.

So I am asking, would it be possible to switch into a bio related major as a transfer after I join the school or should I just go to UCSD for bio? I am really torn between deciding on going to a school just because I got into the major I wanted or going to my dream school (UCLA).

Also, if i were to get and environmental science b.s. would I be able to go for a Masters in biology?

Any input would be greatly appreciated!

Environmental science includes a lot of biology but with a more professional focus. You could take extra biology classes for your electives.
What do you want to do with your biology major ?

Thank you for the reply! I really want to work in a diagnostics lab because of an internship I recently undertook. I really love the science behind diagnostics and the idea of working with infectious disease. I feel like a degree in biology would definitely give me more experience and knowledge in this field and would better prepare me for potential jobs or graduate programs. For this reason ucsd makes sense, but I have had a lot of people say not to just pick a school based on the degree and that undergrad degree doesn’t matter as much as long as you get good grades. If this is true then I think ucla would be better.

I guess it depends how much you want biology then. If the subject is key, then UCSD - which is EXCELLENT for that subject BTW. If your priority is location, reputation, everything else about UCLA, then be it. There’s always a trade off, it’s up to you to decide.
In your situation, since you’re a transfer student and more decided on your major than a typical HS senior, I’d say go with the subject you’ve decided on.

Thank you so much for the input! I think I will visit both schools and then make a decision. Biology is definitely what I want to do so UCSD seems better.
