01Four kinds, and what each is really doing.
They look alike in a margin and they want completely different responses, which is why undifferentiated feedback feels like a wall of criticism rather than a set of instructions.
- Local corrections. A citation formatted wrongly, a sentence that does not parse. These mean what they say, they are cheap to fix, and they are not the important ones however numerous.
- Instances of a pattern. The same objection appearing in three places, phrased differently each time, which a marker writes because they are meeting it repeatedly. This is the one that matters.
- Structural notes, usually at the end and usually short. Something about the argument, the order, or what the piece did not do. Brevity here signals importance rather than the reverse.
- And absences: the row on the sheet that was scored low with nothing beside it in the text, because the thing being marked down was never there to comment on.
- That last category is invisible if you read only the margin, and it is where the largest single losses usually sit.
02Read for the repeat.
Go through the comments once and write down what each one is objecting to in your own words, four or five words each. Then look at the list rather than the paper. Almost always two or three entries are the same objection wearing different clothes.
That single repeated fault is worth more attention than everything else combined, because it is the thing costing you marks across every piece rather than in this one. Somebody who consistently describes where the sheet asked them to evaluate is losing the same row every term, and no amount of tidying citations touches it.
It also tends to be invisible from inside, which is why feedback is worth this much effort. You cannot see your own habit. A marker meets it fresh and reacts to it three times in eight pages.
03Reading across pieces, not within one.
The stronger version of the same technique is to lay two or three returned pieces beside each other, from different courses if possible. What survives across markers is you; what appears once is probably that marker or that assignment.
This is the read that changes terms rather than papers. A student who discovers that every marker for two years has said some version of the same thing has found something genuinely worth fixing, and usually something fixable in an afternoon once it has a name.
It also protects against overcorrecting on one grader's preference, which is a real cost of taking single-paper feedback too literally. Where a comment appears once and contradicts what everybody else has said, it is information about that reader rather than about your writing.
04What to do about a comment you disagree with.
Ask, briefly, and ask about the sheet rather than the mark. There is a large difference between a message saying you think the grade is wrong and one asking what the top band of a particular row would have looked like on this piece. The first is a dispute and tends to be defended; the second is a question and tends to be answered generously.
Do it soon after the mark returns, while the marker still remembers the paper, and do it before the next assignment rather than at the end of the term when nothing can be applied. The shape of that message is the one described at writing to a professor.
Where you genuinely believe a mark is wrong on its merits rather than unclear, that is a separate and much narrower process, and confusing it with an appeal about circumstances wastes an attempt. The distinction is set out in the appeal issue.
05The comment that is not criticism.
Worth naming, because students routinely misread it. A marker writing a question in the margin is frequently not objecting; they are thinking alongside you, which is what they do when a piece is interesting enough to argue with.
Similarly, a mark of yes or good beside a paragraph is data rather than politeness. It tells you what worked, and knowing what worked is more actionable than knowing what did not, because it can be repeated deliberately.
So read the positive marginalia with the same attention as the negative. Most people skim past it on the way to the criticism, which means they never learn which of their own habits was the one earning marks.
Questions at this desk.
There are no comments at all. What now?
Then the marking sheet is the feedback, and the row scores are the message: whichever rows scored lowest are what to ask about. A short message asking what the top band would have required on one specific row usually produces more usable guidance than the original comments would have.
How soon should I look at feedback?
Later than you want to and sooner than most people manage. An hour after opening a disappointing mark is a poor time to extract instruction from it. The next day is fine. Three weeks later, when the next piece is already written, is too late to be worth anything.
Should I rewrite the marked piece?
Only where a resubmission is genuinely offered. Otherwise the effort belongs in the next piece, where it can still affect a mark. Rewriting a returned assignment feels productive and changes nothing, which makes it one of the more comfortable ways to avoid the next deadline.
What if two markers say opposite things?
Then it is preference rather than principle, and the thing to follow is whichever one is marking the piece in front of you. Genuine faults recur across readers. A comment that appears once and contradicts the others is telling you about that reader rather than about your writing.
