Today is the first day of the new semester.
I rushed to room U108 just on time at 8am. I opened the door and found nobody was around. I checked my timetable to see if I've entered the wrong classroom. No,it was the right class. I switched on the computer,put the screen down and turned on the projector,getting everything ready for the first class. Gradually, the students came in till the number reached 16. All girls.
At ,2.10pm the students were already there as I entered AV2 USPP room. Just 13 of them. Again,all girls.
As I entered and greeted the students in my 4 o'clock class at U108,they answered enthusiastically despite being the 4th class of that day. They had 3 other classes since 8.00am and there were 28 students.
What are the differences of the 3 classes I entered today?
What conclusions can be made?
Well, I'll share the reasons here when I meet the absentees later.
