How the Curve Works
Most grading we've encountered worked one way: we earn points, the points add up, and the total tells us our grade. Ninety percent is an A. Everyone in the class could get one.
Law school doesn't work this way though.
Here, grades are allocated. The school sets how many of each grade a class can receive, and our professor distributes them. Our performance determines where we land relative to everyone else — not whether we cleared some fixed bar.
That small change has consequences that aren't obvious, and this page is about them. Not because we should be optimizing every decision — plenty of people reasonably decide a half-step lower is fine when their time is better spent elsewhere — but because we should be making those decisions knowing how the system actually works.
The distribution
Courses with 20 or more students have to follow a mandatory grade distribution. The percentages aren't a suggestion; they're the range a professor's grades have to land in no matter how everyone does.
Two things worth reading off that:
The top is capped. No more than a quarter of the class can be in the top band, no matter how well everyone does.
The middle is where most people are. That's not a judgment about the middle — it's arithmetic. B / B− is the center of a competitive distribution across an intelligent, capable class.
Courses under 20 students don't have to follow the exact percentages, which is why seminar grades often look different from what we'd expect. A handful of courses are even exempt. But, generally, our grades reflect a curve.
The mean
Beyond the distribution, there's a target for the class average.
First-year courses target a 2.80. A professor can land anywhere from 2.70 to 2.90 without needing approval; going outside that takes a written petition.
Everything else has a 3.00 maximum. Note the difference — that's a ceiling, not a target. Nobody is required to bring a class average up to 3.00.
This is why 1L grades tend to run lower than upper-level grades, and it's structural rather than a reflection of how hard people are working.
What actually moves our grade
Here's the part that isn't obvious.
A syllabus tells us homework is 20% and the final is 80%. That sounds like the final matters four times as much. But those percentages describe how points are allocated, not how much each component affects where we land.
What determines that is spread — how much a component separates people from each other.
Everyone clusters near the top. It can’t move us up.
Twenty points of spread. Standing is decided here.
If almost everyone scores 18–20 on the homework, that 20% of our grade produces almost no separation. Everyone has roughly the same points. It can't move us up. It's almost as if those points don't exist.
If the exam scores run from 40 to 60, that's twenty points of spread across the class — and that's where position gets decided.
But the same fact cuts the other way. If everyone maxes the homework and we scored a 15, we haven't lost a small amount of a small component. We've fallen behind the entire class on points they all have. Low-spread components can't help us get ahead, but they can absolutely put us behind. And when homework grades are spread out — not everyone bunched near the top — doing well on it becomes a real advantage, the equivalent of walking into the exam a few questions ahead.
Density
This is the piece that can be the most difficult.
The same three points can be worth a full letter grade or worth nothing at all, depending on how many people are sitting at our score.
Worth a full letter grade.
Changes nothing.
If we're in a crowded part of the distribution — a dozen people within a few points — then picking up three points moves us past a meaningful number of them, and that can be the difference between one letter grade and the next.
If we're in a thin part, three points might move us past one person and change nothing.
We can't know in advance which one we're in. That's the honest answer. Which leads to the only real conclusion this page offers:
Take the cheap points. Low-spread components — homework, participation, anything where most people score near the top — are inexpensive to max and expensive to miss. They rarely gain us ground, but giving them away is a pure loss with no upside. The components with real spread are where standing actually gets decided, and that's where extra preparation pays the most dividends.
What this doesn't mean
It doesn't mean we should be optimizing everything. Law school is three to four years and there are things worth more than a fractional GPA change — health, relationships, the kind of work that gets us a job, the parts of the subject we actually find interesting.
It just means the rules are worth understanding so our choices are actual choices. Deciding that a C in a course is fine because we'd rather spend the time on moot court is a completely reasonable call. Ending up with a C because we didn't realize the homework everyone else maxed was quietly costing us is a different thing.
None of this is about competing with each other. GPA is a small part of what it means to do well in law school, and the point of this page is to take some of the stress out of it — not add to it.
