To upload scanned answer sheets, click on ‘Upload PDF/TIF images of scanned answer sheets’ from the Home screen or Tests screen of your PREP.BubbleScan.net account.
Select the type of test you are uploading (SAT-4page or ACT-2page) and the test date. Then select the PDF or TIF files you want to upload for processing and grading. You can use the green <+Add files…> button or drag files onto the canvas.
On the Review screen you can look at individual pages by selecting them in the left pane and fixing any entries in the middle pane. A page with a questionable entry (in the example below a double-mark in the student ID) is flagged with a red triangle, which changes into a red triangle with green check mark as soon as the page is viewed.
When you have reviewed all data, select all the pages you want and send them back to PREP.BubbleScan.net by clicking on the blue button. The data is now automatically graded against the answer key specified on the form.
