The Quick Answer

The BU Hub requires 26 units across 6 capacities — but don't panic. Most students complete them in 10-12 courses because a single course can satisfy multiple Hub units simultaneously. The key to the Hub is understanding that it's designed to overlap with your major requirements, not pile on top of them. With strategic planning, you can graduate on time without taking a single "throwaway" course. Here's exactly how the system works and how to beat it.

The 6 Hub Capacities & Their Exact Requirements

Every BU undergraduate must earn 26 Hub units spread across these 6 capacities. Here's the exact breakdown:

Capacity 1: Philosophical, Aesthetic & Historical Interpretation (3 units)

Capacity 6: Intellectual Toolkit (8 units)

Important distinction: Hub units are NOT the same as course credits. A single 4-credit course might carry 1, 2, or even 3 Hub units. This is why 26 units doesn't mean 26 courses.

Double-Counting: The Key to Finishing on Time

Here's what BU doesn't make obvious enough: Hub courses are designed to overlap with your major requirements. This is called "double-dipping" and it's not just allowed — it's expected.

How double-counting works:

  • A single course can fulfill both a major requirement AND one or more Hub units
  • Many required courses for your major already carry Hub designations
  • You should check which Hub units your major courses automatically satisfy before planning anything else
Example for a CAS Biology major:

Biology 101 (required for your major) also carries SI1. Organic Chemistry carries QR2. Your required writing seminar covers FYW. Before you've taken a single elective, you may already have 8-10 Hub units checked off.

Example for a Questrom student:

Most Questrom core courses carry QR1, QR2, CRT, and TWC units. By the time you finish your business core, you could have half your Hub units done.

Over 1,600 courses across BU's 10 undergraduate schools carry Hub designations. Use the [BU Course Search](https://www.bu.edu/phpbin/course-search/) to filter by Hub area and find courses that satisfy multiple requirements at once.

Pro tip from students: Before registration each semester, map out which Hub units each of your planned courses satisfies. Many students discover they're closer to done than they thought.

Cross-College Challenge & Co-Curricular Options

Two special options can accelerate your Hub completion:

Cross-College Challenge (XCC)

  • Available to juniors and seniors
  • A single 4-credit course that fulfills 4 Hub units at once
  • Interdisciplinary team projects solving real-world problems
  • One of the most efficient ways to knock out remaining units
Co-Curricular Experiences
  • 0-credit, ungraded experiences that each fulfill 1 Hub unit
  • First-year students can earn up to 2 Hub units through co-curriculars
  • Transfer students can earn up to 1 Hub unit
  • Examples include hands-on workshops, community projects, and discussion-based experiences
  • Cannot be repeated for additional units
Transfer students: If you transferred to BU, your Hub requirement is reduced to 10 units instead of 26. Your transfer advisor will help you map out which units still need to be fulfilled.

5 Strategies to Finish the Hub Without Stress

Pro Tip
Strategy 1: Map your major first

Before your first registration, sit down with your advisor and identify every required course in your major that also carries Hub units. You'll likely find that 40-60% of your Hub is already covered by courses you were going to take anyway.

Strategy 2: Target multi-unit courses

Some courses carry 2-3 Hub units each. These are gold. The Cross-College Challenge (XCC) carries 4 units in one course. Search for these specifically in the course catalog.

Strategy 3: Use electives strategically

When you have room for an elective, don't just pick something interesting — pick something interesting that ALSO fills a Hub gap. Every elective should do double duty.

Strategy 4: Don't leave Communication for last

Capacity 5 (Communication) requires 6 units and includes writing-intensive courses that fill up fast. Start FYW freshman year and plan your WIN and WRI courses early.

Strategy 5: Check your Hub progress every semester

Use your Student Portal to track remaining Hub units. Students who check regularly finish on time. Students who ignore the Hub until junior year scramble.

As one BU student put it on Her Campus: "The Hub curriculum at BU is more flexible than it first appears. With strategic planning, you can satisfy multiple requirements with single courses — but this requires understanding the system early."

What BU Students Actually Think About the Hub

The Hub gets strong reactions from students. Here's the honest picture:

The frustration is real:

"The entire system is confusing beyond measure because it requires students to not only keep track of their course credits and major requirements, but also Hub units, which are not equivalent to credits." — Her Campus BU

"There simply isn't enough time to complete 26 units when one four-credit class typically only fulfills one or two of those units, and for people with dual degrees or minors and less room in their schedules, it can be even more restricting." — BU student editorial

"Some students are discouraged from pursuing academically stimulating experiences — such as study abroad programs — in lieu of accommodating the Hub." — Student commentary on Hub constraints

But it has defenders too:

"One thing I'll say is that some of my favorite classes at BU were Hub courses I never would have taken otherwise. My philosophy class (PLM) genuinely changed how I think about ethics in my engineering work." — Senior, College of Engineering

"Don't worry, everyone is just as confused as you are." — Her Campus BU advice to freshmen

The bottom line: Most students find the Hub confusing at first but manageable once they understand the double-counting system. The students who struggle most are those who ignore it until junior or senior year and then realize they have 8+ units left to fill.

Hub Requirements by BU School & College

How the Hub interacts with your major varies significantly by school:

School/CollegeHub Units Covered by MajorTypical Extra Courses Needed
CAS (Sciences)10-144-6
CAS (Humanities)12-163-5
Questrom12-154-5
ENG10-125-7
COM10-144-6
Sargent10-125-7
CFA8-125-8
CGS14-182-4
Wheelock10-144-6
SHA10-144-6

Estimates based on typical course loads. Actual overlap depends on your specific major and course selections.

CGS students tend to have the easiest time because CGS core courses are specifically designed with heavy Hub integration. CFA and Engineering students often have the hardest time because their studio/lab-heavy curricula leave less room for Hub electives.

Check your specific major's Hub overlay at [bu.edu/hub](https://www.bu.edu/hub/hub-requirements/) to see exactly which required courses carry Hub units.

FAQ

Frequently Asked Questions

How many Hub units do I need to graduate from BU?
All BU undergraduates must earn 26 Hub units across 6 capacities. However, most students complete these in just 10-12 courses because courses can satisfy multiple Hub units and overlap with major requirements. Transfer students only need 10 Hub units.
What's the difference between Hub units and course credits?
Hub units and credits are separate systems. A typical 4-credit course might carry 1, 2, or 3 Hub units. You need 128 credits to graduate AND 26 Hub units. The good news is that Hub-designated courses count toward both your credit total and your Hub requirements simultaneously.
Can Hub courses count toward my major?
Yes — and they're designed to. This is called 'double-counting' or 'double-dipping.' Many required courses in your major already carry Hub designations. Before planning extra courses, check which Hub units your major requirements already cover.
What happens if I don't finish my Hub requirements?
You cannot graduate from BU without completing all 26 Hub units (10 for transfers). If you're behind, meet with your advisor immediately. The Cross-College Challenge (4 units in one course) and co-curricular experiences (1 unit each) can help close gaps quickly.
What is the BU Hub Cross-College Challenge?
The Cross-College Challenge (XCC) is a 4-credit course available to juniors and seniors that fulfills 4 Hub units in a single course. It involves interdisciplinary team projects solving real-world problems and is one of the most efficient ways to complete remaining Hub requirements.
Do Hub requirements change if I study abroad?
Study abroad courses can fulfill Hub requirements, but this requires pre-approval. Some students find that study abroad planning is complicated by Hub requirements. Check with both the study abroad office and your advisor before assuming courses will transfer with Hub designations.
How do I search for courses that fulfill specific Hub units?
Use the BU Course Search tool at bu.edu/phpbin/course-search/ to filter by Hub area. You can search by specific Hub codes (like QR1, ETR, or WIN) to find courses that fill your remaining requirements. Over 1,600 courses across BU carry Hub designations.
Are Hub requirements different for transfer students?
Yes. Transfer students only need to complete 10 Hub units instead of 26. First-year transfers can earn up to 2 Hub units through co-curricular experiences. Your transfer advisor will help you determine which units you still need based on your previous coursework.
