Core Average vs Overall Average: What UBC Counts
“Core average” and “top 6” are student words, not UBC words, and the gap between them costs seats every year. UBC reads all of your academic Grade 11 and Grade 12 courses, then pays extra attention to the subjects tied to your degree. Here is exactly what counts, what doesn’t, how Ontario transcripts get read, and two worked examples with real numbers.
The one-sentence version
UBC’s own wording, from its What we look for page: it considers your grades in all Grade 11 and Grade 12 academic classes, “paying special attention to courses that relate to the degree you’re applying to.” That is the whole model. There is no “pick your best six.” There is an overall picture and a degree-related picture, and both are looked at.
Students compress that into two phrases: overall average (everything academic) and core average (the degree-related subjects). Neither phrase appears on UBC’s high school admissions pages. The official terms are “academic courses” and “key subject categories related to your chosen degree.” The student shorthand is fine to use as long as you remember it is shorthand, because the two mistakes that follow both come from taking it literally.
Which courses count, and which don’t
UBC lists the exclusions plainly. Not counted: career education, physical and health education, faith-based courses, skills-based courses, and courses in Applied Design, Skills and Technologies. Everything else with an academic label is in, including the ones students assume are safe filler: Drama 12, Art Studio 11, Spanish 11, Social Studies 11. UBC groups the counted courses into six categories: Language Arts, Mathematics and Computation, Sciences, Second Languages, Social Studies, and Visual and Performing Arts.
Two more rules from the same page matter more than students think. First, UBC says it will exclude your lowest grade, as long as that course is not a degree-specific requirement or relevant to your intended area of study. One bad elective is forgiven. Two are not. Second, the UBC Calendar states that academic assessment is “primarily based on Grade 12 final or in-progress course grades; however, an applicant’s full academic history may be considered, particularly where sufficient Grade 12 grade information is not yet available” (UBC Calendar). Read that twice. Your Grade 11 marks are not decoration. In the December round, before any Grade 12 finals exist, they are most of the evidence.
What “core” means, faculty by faculty
The UBC Calendar publishes, for each degree, both the required courses and the subject categories the faculty weighs. This is the closest thing to an official “core” that exists. For BC applicants for Fall 2027 entry, confirm on the program requirements page, but the current table reads:
| Degree | Required Grade 12 (and 11) courses | Categories UBC says it focuses on |
|---|---|---|
| Applied Science (Engineering) | English Studies 12 or English First Peoples 12, Pre-Calculus 12, Chemistry 12, Physics 12 | Language Arts, Sciences, Mathematics and Computation |
| Science | English 12, Pre-Calculus 12, one of Anatomy and Physiology 12 / Chemistry 12 / Physics 12, plus Chemistry 11 and Physics 11 | Language Arts, Sciences, Mathematics and Computation |
| Commerce (Sauder) | English 12, Pre-Calculus 12 | Language Arts, Mathematics and Computation, Social Studies |
| Arts | English 12 (Pre-Calculus 12 if you intend to major in Economics) | Language Arts, Mathematics and Computation, Second Languages, Social Studies, Visual and Performing Arts |
Notice what this table does and doesn’t say. Science names two Grade 11 courses outright, so a 76 in Physics 11 is a core mark for a Science applicant, not ancient history. Sauder’s categories include Social Studies, so your Social Studies 11 and any Grade 12 social science are part of a Commerce file. And Arts lists five of the six categories, which is a polite way of saying Arts looks at nearly everything. UBC does not publish how much weight the focus categories carry versus the rest; nobody outside admissions knows the formula, and anyone who tells you “core is 70 percent” is guessing.
Two worked examples
Grade 11: Pre-Calculus 11 at 93, Chemistry 11 at 91, Physics 11 at 89, English 11 at 84, Social Studies 11 at 72, French 11 at 68. Grade 12 in progress: Pre-Calculus 12 at 92, Chemistry 12 at 90, Physics 12 at 88, English Studies 12 at 83, Drama 12 at 79. Career Life Connections and PHE are not counted at all. UBC drops the lowest non-required mark, the French 11 at 68. The remaining science-and-math cluster averages about 90.5; the full academic list averages about 86. This student’s Science file is stronger than their “overall” suggests, because every course Science names is at or near 90. The 72 in Socials is real and it stays, but it is not in a category Science says it focuses on.
Grade 11: English 11 at 94, Social Studies 11 at 95, Spanish 11 at 96, Pre-Calculus 11 at 81, Chemistry 11 at 80, Physics 11 at 78. Grade 12 in progress: English Studies 12 at 93, Law 12 at 95, Spanish 12 at 94, Pre-Calculus 12 at 79, Chemistry 12 at 82, Physics 12 at 77. The overall academic average is about 87, a touch above Student A. But the four courses Engineering requires sit at 77 to 82, and none of them can be the dropped grade because all four are required. On the courses the faculty says it focuses on, this file averages about 83. If you are Student B, this is how an 87 gets refused while a friend with an 86 gets in.
Same transcripts, flipped degree, flipped outcome. Student B would be a strong Arts applicant. Student A applying to Arts would have that 72 and the 79 pulling on categories Arts actually reads. The lesson is not “core matters more.” It is that the answer depends on what you apply to, and your second-choice degree should be picked with this table open.
If you are applying from Ontario
This is where the most expensive misunderstanding lives. Every Ontario university builds your admission average from your top six 4U/M courses. UBC does not. It reads your Grade 11 and Grade 12 courses the same way it reads a BC transcript: all academic courses, focus categories on top. The Calendar maps the equivalents: ENG4U for English 12, MHF4U for Pre-Calculus 12, MCV4U for Calculus 12, and 3U sciences for the Grade 11 sciences. It also says outright that MDM4U (Data Management) “cannot be used to satisfy BC Pre-Calculus 12.”
So the Ontario student with a 94 top-six, built from six carefully chosen 4U courses, who also carries three Grade 11 marks in the 70s and a Grade 12 elective at 68, is not a 94 to UBC. They are a mid-80s overall applicant whose Sauder file also gets read on Social Studies and math. If you are wondering how a 94 lost a Sauder seat to a BC applicant with an 89, this is usually the answer. UBC receives your grades electronically through OUAC if you gave your OUAC reference number on the application, so there is no way to send only your best six (Submit your documents).
What you can still change
- In Grade 11: everything. Treat Chemistry 11 and Physics 11 as Science core, not warm-up. Do not load Grade 11 with electives you will coast through; they count.
- In Grade 12, first semester: the required courses for your first choice are the marks to protect. If a required course is sliding, it is worth more attention than an elective at 90 that could reach 94.
- Choosing a second choice: pick the degree whose focus categories match the courses you are actually strong in, not the one that sounds closest to your first choice.
- The Personal Profile: UBC says admission is a combination of academics and the profile. It is the only part of the file not fixed by a transcript, which is why students with an uneven overall average should spend their December on it.
Before you close this tab
If you are deciding whether to submit by December 1 or wait for first-semester Grade 12 marks, the early vs regular guide shows exactly which grades UBC has in hand in each round and the one thing you cannot change after you submit. If your status already says deferred, the deferral guide explains why UBC does it and the two things that actually move the outcome. And if your profile is the half of the file you control, the Personal Profile guide walks through every question with a worked answer. If you are also applying to Ontario, the Ontario top 6 guide is the equivalent calculation there and the OUAC 105 guide for BC students covers the timeline. The Literacy 12 Assessment is the other UBC requirement that is not a course average, and once the offer arrives, how far final grades can slip before UBC or SFU revoke it is the next question. Then get it marked: AcceptMe’s essay coach reads each answer line by line and tells you which sentences are doing work and which are costing you characters.
