Reviewing OCR Extractions
Understanding the OCR Review Screen
After the OCR engine processes a homework image, you are presented with the OCR Review screen. This is where you verify the AI's readings and make corrections before the grade is finalized. Taking a few moments on this screen ensures accurate grades, even when handwriting is difficult to read.
How Extracted Answers Are Displayed
Each problem from the worksheet is listed with three pieces of information:
- Problem number — Matches the problem number on the worksheet.
- Extracted text — What the AI read from the student's handwriting.
- Confidence percentage — How certain the AI is that it read the answer correctly.
Interpreting Confidence Colors
Confidence scores are color-coded to help you prioritize your review:
- Green (80% and above) — High confidence. The AI is fairly sure this reading is correct. You can usually trust these without checking.
- Yellow (60% to 80%) — Medium confidence. The AI was able to read something but is not entirely sure. You should glance at the image to verify.
- Red (below 60%) — Low confidence. The AI struggled with this answer. It is very likely incorrect and needs your manual correction.
Correcting Misread Answers
To correct an answer, simply click on the input field next to the problem number and type the correct value. When you edit a field, it turns blue to indicate that it has been manually changed. This visual cue helps you keep track of which answers you have reviewed and which are still the original OCR readings.
Resetting to Original Readings
If you edit an answer and then want to go back to what the AI originally read, click the Reset button next to that field. This reverts the answer to the original OCR extraction. This is useful if you accidentally overwrite a correct reading or want to start fresh on a particular answer.
Comparing Against Expected Answers
Below each extracted answer field, the expected (correct) answer from the answer key is displayed. This makes it easy to compare what the student wrote against what the correct answer should be, even before you finalize the grade. Use this to spot-check whether the OCR reading matches what you see in the homework image.
Accepting and Finalizing the Grade
Once you are satisfied that all answers are correct (either as originally read by the AI or as corrected by you), click Accept & Grade. The system compares each answer against the answer key, calculates the score, and saves the results. After grading, the upload entry shows the final score along with per-problem results — green checkmarks for correct answers and red marks for incorrect ones.
Already-graded submissions are clearly marked in your grading history, so you can always go back to see how a student performed on any previous upload.
Tip: Focus your review time on yellow and red confidence answers. Green answers are correct the vast majority of the time, so you can save effort by trusting them and concentrating on the uncertain readings.
