hmm its being for a while that im not updating this blog. due to previous research is completed. therefore i move to another field of research. but before i'm moving to this new area, I do need to complete an IELTS exam. its a must for me to achieve a certain level to pursue my study in PhD. seems quite easy for some people who have strong command in English, but for me. hmm i don't know. hopefully by having some exercise will make me become more understandable of this English language..
