Science reports & dissertations, marked to your rubric
The writing in science — lab reports, practical write-ups and dissertations — is marked on published criteria, even when the exams aren't essays. Upload your rubric with your draft and Mark scores each section — aim and hypothesis, method, results, and a discussion that interprets — quoting where marks are won or lost.
Science reports are marked on structure and interpretation — exactly the criterion-referenced marking Mark was built for.
One thing before we start: I never write a word for you. I mark your draft against your rubric — like a teacher's first pass — so youdo the improving. Check your school's policy on AI feedback, and acknowledge your use of it where required.
How it works
Add your rubric
Upload or paste the criteria your work will actually be marked against — e.g. your unit's lab-report or dissertation marking rubric.
Upload your draft
Drop in the PDF (or paste the text). Mark reads it against every criterion and scores it, quoting the exact lines that earned the marks.
Improve and re-mark
Fix what he flagged, run it again, and watch the mark move. That loop is how essays climb to the top grades.
Not sure why you lost marks? Just ask him.
Every marked essay now has a chat. Ask Mark why a criterion landed where it did, what “more analysis” actually means, or where to start on your re-draft — and he'll talk it through with you, pointing to the exact lines in your essay.
He'll never write it for you. He asks the questions a good teacher would, so the improving stays yours.
See it before your marker does
Mark your draft, fix what he flags, watch the mark climb.
Mark scores your draft against your rubric and quotes the exact line behind every mark. You fix the two things holding it back, run it again — and the number moves. That loop is the whole game.
- Marked against your rubric. Your criteria, not a generic template.
- Evidence for every score. The exact line that earned it — or cost you the mark.
- Revise and re-mark. Improve the draft, run it again, and see the mark climb.
Your essay
Mark is reading your draft…The line Mark quoted
“The railways did not simply move people faster — they reshaped the ordinary rhythm of the day, standardising the clocks between towns and turning a distant city into somewhere you could visit and be home from before dark. Bradshaw's timetable soon sat in every household.”
You name the cause — now push it. Add one sentence on the consequence you hint at, and this criterion tips into the top band.

Draft 2
The discussion is where reports are won
Most lab reports lose marks in the discussion — repeating results instead of interpreting them, ignoring error and limitations, or not linking back to the hypothesis. Mark scores your report against the rubric, section by section, and shows where the analysis is thin.
He marks the writing, not the figures
Mark reads your text — the structure, reasoning and clarity of the report — and flags where a method isn't reproducible or a claim outruns the data. He can't mark figures, graphs or raw calculations themselves.
