I've tutored about 200 first-year undergraduates on their first major academic paper across the last few years. The pattern I've noticed: students almost universally misdiagnose what's going wrong with their writing. They blame their sentence-level skills, their grammar, their vocabulary. The actual problems are usually upstream of any of that. Here are the five most-common ones and what fixing each looks like.
1. They didn't understand the assignment
By far the most-common problem. The student starts writing without having parsed what the professor actually asked for. They write a summary instead of an analysis. They argue when they were supposed to compare. They produce a literature review when they were supposed to make an original argument.
The fix is upstream of the writing entirely. Before any drafting, I now have students write out, in their own words, what the assignment is asking them to do. Then we read the assignment prompt together and check whether their version matches. About 60% of the time, it doesn't. The mismatch is invisible to the student until we surface it explicitly.
This single intervention often improves grades more than any sentence-level work could. The student wasn't writing badly; they were writing the wrong paper.
2. Their thesis was descriptive, not argumentative
The thesis says what the paper will discuss but doesn't make a claim that could be disagreed with. "This paper will examine the causes of the French Revolution." This is not a thesis; it is a description.
The fix: ask the student "what do you think someone could disagree with in this thesis?" If the answer is "nothing," the thesis isn't doing its job. A real thesis takes a position. "The French Revolution was driven primarily by economic crisis rather than Enlightenment ideology" is a thesis. The student can defend it, opponents can attack it, the paper has somewhere to go.
Most descriptive theses can be converted to argumentative ones with a few minutes of work, once the student understands what the difference is.
3. They were proving the thesis instead of testing it
This is the more sophisticated version of the thesis problem. The student picks a thesis, then assembles evidence supporting it, then writes a paper that confirms what they already believed. The paper is a brief, not an inquiry.
The fix: have the student articulate the strongest objection to their thesis. Then ask them to engage with that objection in the paper, not dismiss it. The paper becomes more interesting and more rigorous. It also tends to score higher because professors recognize the engagement with counterargument as a sign of serious thinking.
This shift requires the student to give up the comfort of arguing only one side. Many resist initially. The grade improvements convince them within one or two papers.
4. Their evidence didn't actually support their claims
This problem hides in plain sight. The student has citations, they have quotations, they have data — but when you read carefully, the evidence doesn't actually support what they're claiming. The evidence is loosely related to the claim rather than directly supporting it.
The fix: for each major claim in the paper, the student writes out what evidence would have to be true for the claim to be supported. Then we compare against what evidence the paper actually presents. The mismatches show up immediately.
This exercise feels tedious but produces dramatic improvement. Students learn to construct claims that their available evidence can actually carry, rather than reaching for claims their evidence can't support.
5. They wrote in a register they couldn't sustain
The student tries to sound academic. They use complex vocabulary they don't fully control. They construct sentences that wrap around themselves trying to sound sophisticated. The result is prose that's harder to read than the student's natural writing would be, with no compensating sophistication.
The fix: ask the student to read the paper aloud to me. They almost always laugh at how it sounds within the first paragraph. We then revise to bring the prose closer to their actual voice — clearer, simpler, more direct. The paper improves dramatically. The professors notice.
The instinct to sound academic is well-intentioned but counterproductive. Strong academic writing is usually clearer than student writers expect, not more elaborate.
The pattern under the patterns
Across all five problems, the underlying pattern is the same: students are working at the wrong level. They're trying to fix sentence-level issues when the problems are at the level of assignment understanding, thesis construction, evidence-claim alignment, or voice.
Sentence-level work is real and matters, but it sits downstream of these structural issues. A perfectly polished sentence cannot save a paper that's answering the wrong question. A clear sentence cannot save a thesis that doesn't make an argument. A well-cited sentence cannot save evidence that doesn't support its claim.
The work I do with students focuses heavily on these upstream issues. The downstream sentence work happens too, but only after the upstream is sound. The order matters. Reversing the order — polishing sentences in a paper with structural problems — produces papers that read smoothly but don't earn good grades.
What the data suggests
Across the students I've worked with extensively, the grade improvements correlate strongly with how much upstream work we did versus downstream work. Students who came in wanting only grammar help and resisted the structural work showed modest improvements. Students who engaged with the structural work showed dramatic improvements, often a full letter grade or more across the semester.
This is not a controlled study, and the sample is biased toward students who chose to seek tutoring help. But the pattern is consistent enough across hundreds of cases that I now lead every tutoring relationship with structural work first, sentence work later. The reverse order rarely produces the same kind of progress.
What I tell students starting their first paper now
Three things, in this order:
- Spend serious time understanding what the assignment is actually asking. Write out your interpretation. Verify it against the prompt. Do this before any drafting.
- Build a thesis that someone could disagree with. If no one could disagree, it's not yet a thesis. Then ask what the strongest objection would be and plan to engage with it.
- For every major claim, ask whether your available evidence actually supports it. If not, either find better evidence or change the claim.
If you do these three things well, the sentence-level writing is much more likely to succeed because the foundation is solid. If you skip them, no amount of sentence work will rescue the paper.
The work students think they need is rarely the work they actually need. The same is true for most academic writing problems I see. Start upstream.
