Semester-by-semester courses, IGETC requirements, and major prerequisites — verified from real articulation data.
From
Diablo Valley College
To
UC San Diego
The UC minimum GPA to transfer is 3.0, but the middle 50% of students who actually enrolled at UCSD came in with GPAs between 3.45 and 3.92 — and Biology is explicitly listed by UCSD as one of its most selective majors. The courses that matter most for your competitiveness are BIOL 120, 121, and 122, along with your CHEM 120/121/122 sequence — UCSD screens your major prep GPA separately from your overall GPA, so B's in those courses can sink an otherwise strong application. Shoot for a 3.6 or above in your science coursework, not just overall.
Major Requirements
Biology (School of Biological Sciences, B.S.) at UC San Diego
Courses at Diablo Valley College that satisfy UC San Diego's Biology major preparation, verified via ASSIST.org.
UCSD's School of Biological Sciences offers seven distinct B.S. majors — Biology is the most general track, but students often confuse it with Human Biology (more pre-med/public health focused), Ecology, Behavior & Evolution (field/organism focus), Microbiology, and Molecular Biology. These are separate majors with different upper-division requirements. Make sure you're applying to the right one before you start your major prep.

CHEM 120 → CHEM 121 → CHEM 122: Three Semesters, No Shortcuts
General Chemistry I (CHEM 120) must be completed before General Chemistry II (CHEM 121), which must be done before Organic Chemistry I (CHEM 122) — that's three consecutive semesters of chemistry just to meet UCSD's Biology major prep screening requirements. If you start even one semester late, you risk having Organic Chemistry incomplete at the time UCSD reviews your application, which is a hard screening flag for this major.
UCSD Runs on Quarters — DVC Runs on Semesters
One DVC semester covers roughly the same material as one-and-a-half UCSD quarters, so expect the pace of your courses to feel noticeably faster once you transfer — plan to build your study habits at DVC as if you're already on a quarter system.

Watch Out
A huge number of Biology transfer hopefuls delay CHEM 120 to 'get settled' at DVC — and then find themselves trying to squeeze Organic Chemistry I (CHEM 122) into their final semester. UCSD screens Biology applicants specifically for chemistry completion, so any gap in your CHEM 120 → 121 → 122 chain can cost you an offer of admission. Start CHEM 120 in your very first semester, no exceptions.
UCSD's Biology program is a capped major with limited enrollment, which means if you don't make the cut, you won't be admitted to an uncapped fallback unless you specifically listed one on your application. UCSD recommends your alternate be an uncapped major — something like Cognitive Science or History, not another Biological Sciences track, which is also capped. Pick your alternate deliberately, not randomly.
BIOL 120 and CHEM 120 both satisfy IGETC Area 5 requirements while simultaneously fulfilling major prep — you're knocking out two requirements with one course. Many DVC students don't realize this and take separate, lighter science courses for IGETC just to 'play it safe.' That wastes a semester and adds units. Talk to a DVC counselor about maximizing IGETC overlap with your Biology major prep from day one.
FAQ
The UC-wide minimum GPA to be eligible for transfer is 3.0, but UCSD's Biology program is one of the most selective majors on campus. The middle 50% of enrolled UCSD transfer students had GPAs between 3.45 and 3.92, and UCSD screens your major prep GPA separately — so your grades in courses like BIOL 120 and CHEM 120 are evaluated on their own. Realistically, aim for a 3.6 or higher in your science coursework to be competitive.
No — UC San Diego does not participate in the Transfer Admission Guarantee (TAG) program. TAG is available to six UC campuses, but UCSD, UCLA, and UC Berkeley are not among them. DVC does offer TAG to campuses like UC Davis, UC Santa Barbara, and UC Santa Cruz, so if you want a guaranteed seat, those are your options within the UC system.
UCSD screens Biology transfer applicants for a specific set of lower-division prep courses. At Diablo Valley College, the key courses are BIOL 120 (Molecular and Cell Biology), BIOL 121 (Botany and Plant Physiology), BIOL 122 (Zoology), CHEM 120 and 121 (the two-semester General Chemistry series), and MATH 192 (Calculus I). You should also complete CHEM 122 (Organic Chemistry I) and MATH 193 (Calculus II) before transfer to stay on track once you arrive at UCSD.
Yes — IGETC is accepted for Biology majors at most of UCSD's residential colleges, including Muir, Marshall, Warren, Roosevelt, Sixth, Seventh, and Eighth Colleges. Completing IGETC before transfer means you can focus on upper-division Biology coursework right away after arriving on campus. Note that if you end up at Revelle College, IGETC only partially satisfies GE requirements, and you'll have additional math and science requirements to complete.
UCSD itself identifies Biological Sciences as one of its most selective schools for transfer — alongside Engineering, Data Science, and Public Health. The overall UCSD transfer admit rate is around 54% across all majors (Fall 2024), but Biology admits at a meaningfully lower rate due to the volume of pre-med and pre-research applicants. CHEM 120, CHEM 121, and the BIOL 120–122 series are all screened, and missing even one puts your application at a significant disadvantage.

Planning to transfer from Diablo Valley College (DVC) to UC San Diego (UCSD) as a Biology major takes more upfront planning than most students expect — and the earlier you start, the better your odds. UCSD's School of Biological Sciences offers a Biology B.S. that's consistently ranked among the most selective programs for transfer students, with the middle 50% of enrolled transfers arriving with GPAs between 3.45 and 3.92 across all majors. For Biology specifically, UCSD screens applicants on their major prerequisites separately, which means your grades in BIOL 120 (Molecular and Cell Biology), CHEM 120 (General Chemistry I), and the rest of the prep sequence carry serious weight. Transfer planning for this pathway needs to begin in your very first semester at DVC — the chemistry sequence alone (CHEM 120 → CHEM 121 → CHEM 122) spans three consecutive semesters with no room to skip or delay. On the general education side, DVC students can use IGETC to satisfy lower-division GE requirements at most UCSD colleges, and smart students double-count courses like BIOL 120 and CHEM 120 toward both IGETC Area 5 and their major prerequisites simultaneously. One thing to know upfront: unlike UC Davis or UC Santa Barbara, UC San Diego does not participate in the Transfer Admission Guarantee (TAG) program, so there's no shortcut — your application has to stand on its own. Tools like Pipeline help DVC students map out a personalized semester-by-semester plan that accounts for prerequisite chains, IGETC overlap, and UCSD's major prep screening requirements all at once, so nothing falls through the cracks on the way to a Biology B.S. at one of the country's top research universities.
