GNUTU (GNU Student Diary) is a free program for primary, secondary and junior high school students. It serves as a handy schedule where, unlike the usual one, information about assessments, tests, tasks to be performed and other information can be stored. Moreover, the program has an extensive search engine, it can generate statistics on grades (including the calculation of their average), allows you to keep a diary, and allows you to export the timetable to HTML format.

In order to run the program properly, you need the Gtk# Runtime for Windows libraries installed in the system, which in turn require prior installation of the .NET Framework 1.1 libraries. Books can be found in the section PROGRAMS -> Add-ons -gt;

Libraries and other add-ons. The source code, as well as the Linux version of the program can be downloaded from the manufacturer's website.
