I've successfully been using Flexipad since two years. It's not only convenient for me but also for my students. Since I record all assignments and assessments they are very interested in their progress. It's just a few clicks to let the programme calculate a mark or percentage of well done's / attendance.
Do you have a two week timetable due to different groups of students? In this case my class is just group A / B with a number students. If you need assistance please post a question into the forum at
http://palm.itpro.at/forum/ or I can do it in case you don't want to register.
