1) understand all the topic. 2) try connect each other from chapter to chapter( Example chapter 4,5,6 form 4*). 3) focus the topic that you REALLY weak at. 4) do more exercises 5) try use new word in daily life (example: Inkuiri,Nasionalisma,Neokolonisme etc..) 6) if all fail, try make jokes with friends to make it more interesting. (Example: Otto Edward Von Bismarck become Otto Bismarck( dog name + people name) hehe.
