Change of Timetable

This week is the first week of my new timetable slot and it was quite okay for all the days except for Thursday. It has two 1 hour break in between lessons which is FREAKING IRRITATING!!! I requested to change but the bloody timetable people say it will be hard for them to record my marks and whatever shit if I requested to op for other time slot, PIECE OF SHIT!!! No choice, have to bear with it till end of semester...
