i should have learnt this a long, long time ago

i dunno about other universities or colleges, but U*** students are supposed to learn a third language..'to prepare ourselves better in facing the extreme competition, fighting for jobs and etc'
when i was in SA, i took up Japanese and thankfully i completed all three parts of it with As..BUT, i can't quite use it officially..coz i dun have and wouldn't have the cert. so, no comments or statements about Japanese language in my future resume whatsoever..
actually i wanted to learn Mandarin, but it was tough when there was so many students and there was only a few classes to cater for us. that's why Japanese language came into the picture. and now, when i'm in Lendu..i have the chance to learn Mandarin again. the other language being offered is Arabic..but there's just a few that are interested to take it. at first i was worried about the registration part, and thinking about the incident before that made me had to choose Japanese as the 2nd choice..i registered as early as possible. but the first class was chaotic. i thought only half of the 3rd semester's business students would be able to take Mandarin, and the others would go for Arabic, but everyone are able to register for Mandarin got the same schedule and even class. so all of us sat in class, making noises and all..and kinda shocked our lecturer when she saw the number of students waiting for her. 
then in the 2nd class, she informed that my class would continue learning with her..and the other had to be with another lecturer and have one class at night. thankfully i dun have any classes at night this semester. coz everyday proves to be tiring even tho we haven't really started learning much..maybe i've been cooped up for too long :p
now, everyone's busy repeating all the Mandarin words and greetings that they have just learnt. one after another would go.."ni hao, ni hao". "ni mang ma?" and they can be really funny or irritating sometimes..coz everyone, i mean most of other courses also learn the language. and when they keep repeating it, and then another group do the same thing..u can only stand so much. i think i dun even have to revise the lessons by myself if this continues, just listen to them daily..they're like an MP3 player or something. it's good for practice, but God help me!
