heyy.. i did my k3m last year.. and thank goodness, i got distinction
no complaints there XD anyways, coming back to the topic.. firstly, ARE YOU IN FORM 5 or FORM FOUR ? because, if you're in form 4, you're gonna have a tough time coz there ARE quite a number of questions that require your understanding of the form 5 syllabus..
But i do agree with the others, you do have to be good in your chemistry if you wann a get one of the awards..
if you have any ques, just post it here or on my wall aight.. all the best!
