Your markscheme. Your marks. Less of your evening.
Tickd marks your class’s handwritten maths papers against your markscheme, the way you would. You check every mark before anything goes back to students.
Why
Read as BC2 = 74 + 46.69 = 120.69, BC = 10.99
Correct cosine rule substitution (M1 A1). 70 cos 40 is 53.62 in degrees. Their + 46.69 matches cos 40 in radians (-0.667), so BC = 10.99 is wrong (A0).
Why
Read as f′(x) = 3x2 - 12x
Two of the three terms correct, constant term missing: A1 of the A2, as the note allows.
How it works
- 1
Scan the stack
On the school copier, the whole class in one PDF.
- 2
Add your markscheme
The one you already use. You check how Tickd read it.
- 3
Check every mark
Agree with one key, or change it. The unsure ones come first. Try it.
- 4
Print or export
Marked papers to hand back, marks for your gradebook.
Marks like an IB examiner
Tickd reads the working, picks the method the student used and decides each mark point with a reason. Then fixed rules check the result, the way a senior examiner would: no marks that are not in the markscheme, no A mark without its M mark.
Markscheme, question 2 [3]
- (M1)
- attempt to use the cosine rule
- A1
- correct substitution: BC2 = 72 + 52 − 2(7)(5)cos 40
- A1
- BC = 4.51 (cm)
Award the final A1 only for 4.51 (accept 4.514). Do not accept 4.5.
M1 A1 A02/3
Cosine rule (M1), correct substitution (A1). 4.5 is 2 significant figures and the note rejects it (A0).
Markscheme, question 3b [2]
- M1
- substitutes x = 1 into their f′(x)
- R1
- f′(1) = 0, so there is a stationary point
The R1 requires the substitution to be seen.
M0 R00/2
States the given answer with no substitution seen (M0). Conclusion is stated (R1 proposed).
Rule R1 needs M1, which was not awarded. Set to R0. Flagged for you to check.
What you get back
Ticks, crosses and short remarks, in the margin, where students look. And a summary of the class, so you know what to go over next lesson.
Question 3c: 5 of 8 students lost marks. 3 left it blank.
| Question | Average | Lost marks | Remark Tickd wrote most |
|---|---|---|---|
| 1a | 1.8/2 | 1 of 8 | “moved the 7 the wrong way” |
| 1b | 1.6/2 | 2 of 8 | “check the subtraction” |
| 2 | 2.4/3 | 3 of 8 | “calculator mode?” |
| 3a | 1.5/2 | 3 of 8 | “missing a term” |
| 3b | 1.3/2 | 4 of 8 | “check your f′(x)” |
| 3c | 1.6/3 | 5 of 8 | “check f(3)” |
| 4 | 2.3/3 | 2 of 8 | “overlap counted twice” |
Privacy and control
How Tickd handles your students’ papers. The full privacy policy has the details.
- You give every mark
- Tickd suggests a mark. Nothing is final, and nothing reaches students, until you confirm it.
- Names come off in your browser
- You choose the name area. It is blacked out before anything is uploaded, on every page unless you choose otherwise, so names are not sent.
- Only your account sees your exams
- Accounts are by invite only. Each teacher’s exams, scans and marks are kept apart by rules in the database, and no other teacher can open them.
- Who reads the pages
- Claude, Anthropic’s AI model, reads the pages through Anthropic’s API. Anthropic says it does not use this data to train its models without permission, and does not keep the pages or its answers after replying, unless its safety systems flag a request or the law requires it. Anthropic’s data retention page.
- Deleted after 30 days
- Scans and marks are deleted automatically 30 days after upload. You can delete an exam yourself at any time.
- Permission first
- Before uploading, you confirm that your school allows you to upload this student work.
