Degree Paths — plan.andypandy.org

The three contracts

Rules as published by L&S Advising, Haas and CDSS. Where colleges differ, the stricter one governs.

	Double major	Simultaneous degree	Major + minor
What it is	Two majors inside the same college; one B.A.	Majors in two colleges; a degree from each (B.A. + B.S.)	One major plus a department-defined minor (usually 5 upper-division courses)
Course overlap	2 upper-division, total	2 upper-division, total	1 upper-division, total across all majors and minors
Extra time	L&S grants a 9th semester (136-unit ceiling)	9th semester only if both colleges agree — CDSS never does	None. If it does not fit, you drop it
Admission	Declare from your first semester; each major’s own gate	Admitted to both colleges through their normal process	Declare with the minor department
GPA	Each major’s own; graduate with 2.0 in each	L&S 2.0 and one semester done; Haas 3.00 after admission	Minor’s own, typically 2.0
Petition timing	Before the first day of your graduation term	At least two terms before graduation; Haas packet by July 1	Before the first day of your graduation term
Where it shows	Transcript; one diploma	Two diplomas	Transcript and diploma (Fall 2023+)

The fact that reorders everything: Data Science, Statistics and Computer Science (B.A.) are College of Computing, Data Science and Society majors, not L&S. For you, Econ + Data Science is a simultaneous degree, entered only through CDSS comprehensive review. CDSS caps every student at 8 semesters and says so explicitly for simultaneous-degree students; it will not extend for an added major or minor.

Your combinations

Ranked by how the machinery treats them, not by prestige.

Pairing	Contract	Gate	Overlap math	Read
Econ + Business (Haas)	simultaneous	Haas admission (March 2028, once), then 3.00 GPA; both degrees conferred the same term	ECON 100A/100B swap for UGBA 101A/101B = exactly the 2-course cap	The primary branch — and now the target, because Haas alone is 12 months of OPT and Econ is 36. Plan: The Fork.
Econ + Data Science	simultaneous	CDSS comprehensive review, Jan 1–Feb 13 (2025: 94% of eligible admitted)	Economics domain emphasis: ECON 100A + ECON 140 = the cap; a third Econ elective breaks it	Strong secondary if the Jan 2027 window is reachable. Hard 8 semesters.
Econ + Applied Math	double major	Declare; no college GPA gate	Econ cluster has 3 Econ-countable courses; take MATH 170 or STAT 134 as the third	The only true double major in your set. Gets a 9th semester — which F-1 makes expensive.
Business + Data Science	simultaneous, two non-L&S colleges	Two competitive admissions; Haas 3.00; CDSS 8 semesters	Little natural overlap	Hardest on paper. Haas names only L&S and Engineering as examples.
Computer Science (B.A.)	not reachable Jan 2027	CR needs MATH 51 + 52 and one of CS 61A/61B/70 completed, 3.0 GPA (2025: 193 of 211 eligible)	—	Jan 2028 at the earliest on your schedule. CS minor is the realistic form.
Econ + Data Science minor	major + minor	Declare once C8 plus two more courses are done	1 upper-division overlap	The recommended fallback if Haas says no — not the DS BA. The BA requires CS 61B and 8 upper-division courses in 4 terms; the minor is uncapped, needs no application, and the spine already covers 4 of its 7 courses.

CDSS review, Jan 2027

One window a year. You can apply in your second semester.

Data Science needs: DATA C8 (this fall) plus one of Calculus 1, Calculus 2, or Intro Programming with a final grade posted by application. MATH 54 is not on that list.
Your AP Calculus BC 5 maps to MATH 1A/1B for Econ. Whether it counts here is not stated on the CDSS page — ask CDSS advising this week.
If it does not: the only way to make Jan 2027 is adding a CDSS-listed intro programming course (e.g., DATA C88C) before the Sep 16 add/drop deadline. Otherwise the window is Jan 2028, and you must still finish in 8 total semesters.
If admitted: choose simultaneous degree (keep L&S and Econ), not change of college. Packet at least two terms before graduation.
Statistics is also CDSS-only (2025: 98% of eligible) and needs MATH 51 done, C8 and MATH 52 in progress.

Minors that exist

One upper-division overlap with any major. None adds a semester.

Data Science — 7 courses, 4 upper-division; open, not capped; not alongside a DS B.A.
Statistics — 4 lower-division math + 5 upper-division stat; a GPA floor in the math prerequisites (page cites 3.2 — confirm).
Mathematics — MATH 51–54 + 104, 110, 113, 185 + one more; 2.0.
Computer Science (College of Engineering) — 61A, 61B, 61C, 70 + 3 upper-division; 2.0; no enrollment priority, completion “not guaranteed.”
IEOR (Engineering) — 3.0 overall and 3.0 in prerequisites.
Economics: no minor exists. Haas: no business minor — only the summer Sustainable Business & Policy minor and the SCET entrepreneurship certificate (6 units, any major).

The F-1 clock

Your I-20 ends 17 May 2030. Under the fixed-period rule, a 9th semester means a BIO program extension plus an I-539 extension of stay — a USCIS filing, not a form. CDSS would refuse the 9th semester anyway; Haas allows one but requires both degrees to be conferred the same term. So every pairing above is planned for eight semesters, and the L&S “136-unit” allowance is a fallback you should not need.

OPT months follow the degree’s CIP code: Economics is STEM (36 months); Data Science and Statistics are STEM; Business is not (12 months). A minor changes nothing.

Dates

Sep 16, 2026Add/drop. Last day to add a programming course if AP calculus does not count for the DS review.
Jan 1–Feb 13, 2027CDSS comprehensive review (Data Science, Statistics). Decisions ~Mar 30 and Jun 1.
Spring 2027DATA/STAT C140 — the one course on the Econ, Haas and Data Science lists at once. DATA 89 only if Econ says C140 does not count.
Mar 2–31, 2028Haas continuing-student application. Once only.
By 5th semesterEcon declaration (or before 80 units). Guaranteed with a C in each prerequisite.
Before final termAny minor or double-major petition. Simultaneous-degree packets two terms out.
