First of all, I would like to express my appreciation to my wonderful lecturers. i am blessed to have the chance of having all of you as my lecturers. I also want to thank Dr. Izyan Izzati for always being considerate to me and my friends. Even though there are a lot of assignments for this subject, I was not stressed as Dr gave me enough time to complete it. With Dr. Izyan izzati and other lecturers' guidance and constant motivation, I succeed to survive my first semester as a student of UTM.
