Key takeaways
- A real Class IX Social Science half-yearly mock copy (80 marks, 38 questions, 7 pages) was photographed on a phone in a spiral notebook and checked by Evalezy, unedited.
- Evalezy found every answer, marked it against a scheme per question in half-mark steps, and wrote back onto the pages: ticks, crosses with the correct answer, short notes and the total, 38/80, circled on page one.
- No scanner was needed: the photos were straightened, cleaned and contrast-boosted before reading.
- It made one visible slip: Q17 on page 2 is right but was crossed. A teacher’s review catches exactly this before release.
- For a school, the takeaway is practical: phone photos are enough, students get written feedback on every answer, and the teacher’s job becomes reviewing, not reading from scratch.
Background
Most schools do not have a document scanner in every staff room. If AI copy checking only worked on clean scanner PDFs, most copies would never reach it. So the question for this copy was simple: can a teacher take phone photos of a student’s notebook and get back a copy that looks checked by a teacher?
The copy
| Subject and class | Social Science, Class IX, half-yearly mock test |
| Paper | 80 marks, 38 questions in five sections |
| Sections | A: Q1–20 (20 marks) · B: Q21–26 (12) · C: Q27–32 (18) · D: Q33–36 (20) · E: Q37–38 (10) |
| Copy | 7 pages of a spiral notebook, photographed on a phone |
| Handwriting | Mixed: crossed-out words, insertions above the line, answers running across pages |
What Evalezy did
- Cleaned the photos. Each page was straightened, denoised and contrast-boosted.
- Drafted one marking scheme per question, with criteria that add up exactly to that question’s marks. The same scheme is used for every student in the class.
- Found each answer by its content, not by the number the student wrote, so answers written out of order are still found.
- Marked every answer in half-mark steps, with a reason and feedback per question.
- Wrote the result back onto the copy in a handwriting-style red pen.
In a class upload, Evalezy also reads each student’s name and roll number from the top of page one and matches the copy to your class list; a copy it is unsure about waits for a teacher to pick the student.
The result
The checked copy looks like a teacher marked it:
- The total, circled: 38 out of 80, top right of page one.
- Ticks on the lines that earned marks.
- Crosses with the correct answer beside them, for example “Wrong answer. Correct: latitude (distance from the equator).”
- Half marks with a reason: 1.5/2, 0.5/3, 3.5/5, each with a note on what was missing.
- Marks per question in the margin.
The slip
On page 2, Q17 is answered correctly (“Egyptian Civilisation”) but Evalezy crossed it. We left it in the published copy on purpose. It is the kind of mistake that makes a teacher’s review essential, and it is why, in Evalezy, AI marks are a draft: the teacher sees each answer as read, with the mark and the reason, changes the mark and only then releases results to students.
Lessons for schools
- Phone photos are enough. Ask teachers to shoot in even light with the whole page in frame; see our guide to scanning answer sheets with a phone.
- Students get feedback on every answer, not just a total, which is hard to give by hand across 40 copies.
- One scheme for the whole class means copy 1 and copy 40 are judged the same way.
- Review before release, always. One crossed right answer on 38 questions is small, but it matters to the student.
- Diagrams and maps are judged by their labels and written explanation only, so check map work yourself.
Where Evalezy fits
Teachers upload a whole class’s copies at once, up to 200 PDFs, or will soon scan them straight from the Evalezy app. Each student gets their own copy checked in red pen, emailed when you release results. ₹1 per page; failed and unreadable copies are free.

Frequently asked questions
Do I need a scanner to use AI copy checking?+
Not with Evalezy. This copy is a set of phone photos of a spiral notebook, with shadows and ruled lines. Pages are straightened, denoised and contrast-boosted before reading. Even, bright light and the whole page in frame help most.
How long does it take to check a copy like this?+
Typically 1–8 minutes per copy, with several copies checked in parallel; first results in a batch arrive in about 10 minutes, and 100 copies take about 2–3 hours on current capacity.
Can I see the full checked copy?+
Yes. All seven pages are on the sample page, and you can download the checked copy as a PDF.
