Read the comments and sort them into two piles. A criterion is something the rubric asked for that you did or did not do — a source, a framework, a required section. A preference is the marker telling you how they would have written it.
Both are worth learning from and only one is arguable. If the rubric required current peer-reviewed support and you cited a textbook, that is a criterion and the mark is correct. If the comment says this section would flow better earlier, that is a preference, and it is useful for next time rather than grounds for anything.
Almost every regrade request that goes badly was written within an hour of the mark appearing. The delay is not about politeness; it is that you cannot read your own work accurately while defending it.
After two days, read the submission with the rubric beside it and try to mark it yourself as a stranger would. A surprising proportion of the time the criterion the marker cited is genuinely unmet in a way that was invisible while writing. That is an uncomfortable and extremely valuable twenty minutes.
Specific, narrow, and about criteria rather than about the total. Name the rubric row, quote the part of your submission you believe addresses it, and ask the marker to look again at that row specifically. One or two rows, not the whole paper.
Do not mention effort, other students' marks, your average, or what you need for a scholarship. None of those bear on whether the row was met, and including them shifts the conversation from evidence to pleading.
Most have one, most students have never read it, and it usually has a deadline measured in days. There is generally a distinction between an informal query to the marker and a formal appeal, and the formal route often requires grounds narrower than being unhappy — procedural irregularity, or a criterion demonstrably misapplied.
Find the policy before you need it. Knowing that you have ten working days and that dissatisfaction alone is not grounds changes both what you write and whether writing is worth it.
The realistic outcome of a well-made request is a small adjustment or a fuller explanation, and the realistic outcome of a badly made one is a marker who reads your next submission with less patience. That asymmetry is worth weighing.
The higher-value use of feedback is almost always the next assignment rather than this one. A comment you disagreed with in week four, applied grudgingly in week six, frequently turns out to be the thing that moves the mark — and if you would rather have that read by somebody else first, a read-through against your rubric catches the same gaps before submission rather than after.
A formal remark can in principle move a mark in either direction at some institutions, so check the policy before invoking it. More commonly the risk is relational rather than numerical: a marker who receives an aggressive or scattergun challenge reads you differently afterwards, which matters when they mark you again next month.
Follow up once, politely, after about a week. If there is still nothing, that is what the escalation route in the policy exists for — usually a module lead or a program director. Escalating after a documented attempt at the informal route is very different from escalating first.
Usually not, and the arithmetic tells you why: work out what those marks do to your final grade and to your cumulative average. Frequently the answer is a fraction of a point. Where it genuinely straddles a boundary that matters, that is exactly when a narrow, well-evidenced request is worth making.
