The commerse maths lecture....

the last lessons we learn about the percentage and that day a lot of people didn't attend the lecture because all of the students are doing their IT and the economics assignment....
the at least got 70% student didn't attend the maths lecture..
some of the student which got attenr the class is also very sleepy because they are rushing their assignment and didn't sleep at all or just sleep for one to two hour..
the maths that had been teach by Ms Crystal is the lessons that have been teach at the secondary school....
