Notes
Reflection
After i learned all the things in discrete structure, i found that most of the topics had learned already in secondary school. Hence, I think it is not too difficult and just needed to be careful when answering the questions because I very negligent when doing the mathematics questions.
By the way, although some topics i had already learn in secondary school, but i learn the new method to do the same type of questions and the methods is more simple than the method taught in secondary school.
