Here I strongly give you Amway Baidu network disk, which can easily remove handwritten test papers. And it's free. Let's talk about how to operate first.

Step 1: Open the Baidu network disk and select the scan icon.

Step 2, slide to the left to find the function of handwritten test paper.

Step 3: Select the test paper to be handwritten, shoot it or select it from the photo album, and check it directly if you don't need to adjust the angle after selection.

Step 4, automatically remove the start. After the automatic removal is completed, you can cut and smear, and then select Next.

Step 5, complete the handwriting, and then you can convert it into various documents to save. I prefer PDF, so I choose PDF.
