The scarcity is hours, not points

In finals week every student is playing the same constrained game: fixed hours, several courses, each course offering points at a different exchange rate. The losers of this game are almost never the students who studied too little — they’re the ones who studied the wrong course. Twenty hours spent polishing an already-secured A is twenty hours that didn’t save a failing C.

Triage means ranking courses by points per hour — how much course grade a study hour is likely to buy — and funding the best rates first. Three variables set the exchange rate, all of which the calculator already computes.

Variable 1: Distance to the next boundary

Course grades are step functions. An 89.9 and an 80.0 both print as “B range” until a line is crossed — then the transcript remembers only which side you landed on. So the value of an exam point is near zero almost everywhere, and enormous within a few points of a cutoff.

The audit: for each course, note your current grade and the next letter boundary above it. At 88.2 with the A− line at 90, you’re 1.8 points from a letter. At 81, you’re 9 points away. Those are different investments even though both are “a B+ student chasing A−.”

The letter-boundary table automates this: it lists the required final score for every letter at once. Scan for the first row marked reachable above your current letter — that’s your stretch target — and note the margin on your current letter’s row.

Variable 2: Remaining weight still in play

A boundary two points away is only interesting if something can still move you across it. Leverage lives in the remaining weight:

• Final worth 40%: a 10-point exam swing moves the course grade 4 points.
• Final worth 15%: the same swing moves it 1.5 points.
• Final plus a pending project at 35% combined: leverage compounds — use the multi-assessment mode, because the open weight is what matters, not the final alone.

High remaining weight cuts both ways: more upside and more downside. A 40% final in a course where you’re fragile is high-variance — worth defending hours. A 10% final barely moves anything; triage it low unless the pass itself is at stake.

Variable 3: The gap between likely and required

Required score is meaningless without your realistic exam score. If you need 78 and your exam average all term is 74, the gap is 4 points — closeable with targeted work. If you need 95 and your average is 74, the “required” number is a fiction; the honest target is the next boundary down.

The triage table for a typical five-course load looks like this:

Course	Now	Next boundary	Final wt	Needs on final	Your exam avg	Verdict
Chem	89.1	A− at 90	25%	92.7	70	Near-dead — 23 points above your average
Math	84.6	B+ at 87	25%	94.2	76	Near-dead — 18 points above your average
Hist	91.4	A at 93	25%	97.8	88	Dead — maintain the A−
Econ	68.3	C− at 70	40%	72.5	66	Priority — the only flip still in reach
Span	76.9	B− at 80	—	locked? —	—	Check floor, then deprioritize

The ordering writes itself: Econ first — the only letter a realistic score still flips — then maintenance across the board. Chem, Math and History all demand finals 10–23 points above your exam average, the same species of dead at different depths; Spanish just needs its floor confirmed.

The points-per-hour estimate, made concrete

You can put a rough number on each course. Estimate your score gain per study hour honestly — for most students, a focused hour on a weak exam topic is worth 2–5 points on the final, less as you approach the ceiling. Then:

course-grade points bought per hour ≈ (exam points gained per hour) × remaining weight

Chem, 25% final: 3 exam points/hour × 0.25 = 0.75 course points/hour — and the 0.9-point course gap to A− is where naive math lies. Closing it takes a 92.7 on the final, 22.7 points above your exam average: at 3 points/hour that’s eight hours of gains at exactly the altitude where gains die. Econ, 40% weight: 3 × 0.40 = 1.2 course points/hour; the 1.7-point gap asks for a 72.5, 6.5 above your average — about two honest hours, genuinely buyable. History needs 97.8 — dead at any rate. One live fight and four maintenance jobs, decided in ten minutes.

The non-obvious levers, ranked by yield

Once the course order is set, the within-course triage matters just as much:

1. The instructor’s review materials. Review sessions, posted topic lists, past exams — these are the test, lightly disguised. Highest points-per-hour in existence. Attend in person; the questions other students ask reveal the grading rubric.
2. Your weakest scored topic, not your weakest feeling. Look at what actually lost points on past exams. An hour fixing the topic that cost you 15 points twice is worth three hours reviewing the unit you already mostly know.
3. Office hours with specific questions. “Explain question 3 from the practice exam” gets an answer; “how do I do better” gets a pep talk.
4. Practice under time pressure. Reading a solution and producing it cold are different skills. One timed pass through a past exam exposes which is which.
5. Re-reading notes and highlighting. Lowest yield per hour. It manufactures fluency, not recall — the material feels familiar right up until the exam asks you to produce it.

The one rule that overrides the math

Never let a pass-at-risk course go unfunded to polish a letter. A B that slides to B− is a rounding error on a transcript; a failed course is a retake, a GPA hole, sometimes a delayed graduation. When hours are scarce, fund every pass first (branches 3–4 in the decision tree), then spend the surplus on boundary-chasing.

Triage feels cold. It’s supposed to — it’s the discipline of spending a finite resource where it converts to the most transcript value. The students who look calm in finals week aren’t smarter; they ran these numbers two weeks ago.

Frequently asked questions

How do I decide which class to study for first?

Rank by points-per-hour, not by anxiety. For each course compute (a) the gap between your likely score and the required score for the next letter boundary, and (b) the remaining weight still in play. The best targets are small gaps with large weights — a course needing 3 more exam points to flip a B+ to an A− beats one needing 25 points to flip a C to a B.

Is it worth studying for a final that can't change my letter?

Rarely. If the letter is locked in both directions — the required score for the next grade up exceeds 100 and a 0 keeps your current letter — extra hours buy nothing on the transcript. A maintenance skim to protect against a catastrophic exam is cheap insurance, but the bulk of your time belongs to courses where a boundary is still in play.

What moves an exam score the most per hour?

In rough order: the instructor's own review materials and past exams (they telegraph the actual test), targeted practice on your weakest scored topic, office-hour questions on specific confusions, then re-reading notes — which feels productive and mostly isn't. Past-exam questions under time pressure are the highest-yield activity for most courses.

How do dropped grades and curves change the triage?

They change the inputs, not the method. A dropped lowest quiz effectively raises your current grade — recompute it before triage. A curve applies after your score, so plan in raw points: estimate what raw score the curve needs, because a historic '10-point curve' was earned by a class average you can't see.
