Is a B sophomore year detrimental?

HEY ok so I’ve have gotten straight A’s throughout freshman year and I’m REALLY striving for UCSD/UCSB, but right now I’m taking 7 classes and have a B+(89.5 KMS) in AS(advanced standing, like honors but no grade bump) at a very competitive high school in the silicon valley (Northern CA), and it’s nearly impossible to change my grade at this point, and I’m just wondering how this will effect me.

Next year (junior year) I plan on taking AP Bio, AP Lang, AP Calc AB/BC(still deciding), Spanish IV Honors(only honors classes at my school are languages, it sucks), and World History III, which puts me at a 4.7 GPA (assuming I get all A’s which I might be able to do considering I love math and science). Also, is five classes too few? IDK. Senior year I’m still unsure what I’m taking but def. 4+ AP’s focusing on Math & Science.

I’m currently involved in a couple clubs, mainly one charity club, but it’s kind of a joke, and I’m looking into a marine bio institute near my house for volunteer opps. I’m a Latina (race might help?) girl wanting to major in Biostatistics/BioChemistry. My main extracurricular is volleyball, and I’m getting recruited by D1-D3 colleges for indoor and beach. I’ve been to nationals PLENTY of times, named to the USA national training program etc. and I’m on a really good team this year (ranked 36th in the country last year). I spend at LEAST 10-11 hours a week working out, practicing, and competition season starts soon and I will be out of state almost every weekend. I don’t know all my options yet, so in case volleyball doesn’t work out I have to ACTUALLY be smart.

SO after knowing a little bit about me what are my chances for UCSD/UCSB? I’m also considering NYU, UChicago(HAHA but seriously), UCLA, Cal Poly & Tulane. Haven’t taken the SAT/ACT but I’m kind of a bad test taker so I will probably need a bit of a higher GPA to compensate. Thanks for help!
