The PSP tool is meant for planning and following up on your studies. On the scheduling page, you may create a high-level timetable for your studies. You may add the timing of your own group as a basis of your own plan. Selecting studies page allows you to choose modules to your profiling and optional studies (Professional Skills). The overview page shows the contents you have chosen for your PSP.
The Credits tool shows the module grades and grades for partial module completions (unfortunately you cannot see the partial completions on the PSP).
Enrolments page allows you to enrol on your PSP's modules and via Exams you may enrol on resits if your degree programme organises joint exams on campus.
