I'm a teacher in the first year of the university. During the remote classes in the pandemic, we made almost mandatory to upload the photos of the take homes and questions using camscaner [1].

The student just download the app, and it fix the orientation, rotation, bad light, contrast, and many other horrible things that a jpg may have. In particular the orientation and ordering multiple sheets. Also, Moodle has a little more support for pdf than jpg [2].

I don't know how many three letter agencies are reading the stream, but I'm happy that many three letter agencies operative now have a better formation in algebra and calculus.

[2] It depends on how many optional packages your sysadmin installed.
