How to correct the uploaded homework?

You can edit the uploaded PDF files directly in the browser. Follow the link 'correct'.

But of course you can also download the files (individually or several in a ZIP file) and edit them with other programs.

Here is a short list of programs i known:

- Adobe Acrobat (Win,Mac)
- OneNote (Win,Mac)
- PDFXchange Editor (Win)
- Xournal (Linux,Win)
- Xournal++ (Linux,Win)
- INKredible (Android,iOS)
- Xodo (Android,iPad,WinPhone)
- FoxitReader (Win,Mac,Linux)

Examples

How does the pages corrected with these programs look like?

Here are some examples. I scanned a sheet of paper and converted it into a PDF. Afterwards I 'corrected' this PDF file in the different programs.
