anger

i just went back from my daily class. well today my anger was quite beyond of my control. the lecturer gave us assignments last thursday and we have to submit this morning. after submitting, he asked do we have diffculties in doing the assignments. so i pick up my hand and say yes. i really have some difficulties. ye la mana tak ada masalah, dia ajar bab theoritical part je. mathematical part dia belum ajar lagi. so when i asked him question or my curiosity about the question, he simply replied if i couldnt understand the question thats mean i dont read the text book. hell no! ive the book 5 times and no such things example like the questions. so he asked me to read again and i noticed that stil no such things what he wanted me to find out. so he asked me to search for word DISCARDED in the chapter given. after reading 7th times stil i have no answer then he came to one of my classmate and read our text book. and what was the silly part is he is using the old edition of the text book. we are now using 9th edition and he stil using the 5th edition. so then he realized that he didnt do not even one exercise with us. haaa. at that time i can only think how good if i can laugh at him! and tell him dat we didnt came to class to playing around. even we did sumtime *winks* im a bit angry with him. the subject should be more interesting coz there are more mathematical part than the theory part. i luv calculation. but he did it as the whole subject was theoritically. menyesal btol tukar kelas. i ingat nak ikut kawan2 in the same class. sekali lecturer nya membosankan to DA MAX! OMG help me pls!
