Learn some key dates and events ie Verdun, the Somme, look at source analysis, the big three, treaties and alliances (War guilt), peace movements. Its a big topic so just do summaries under BOS topics
i found a great syllabus outline of what you should know about world war I, i'll attach it...
other than that, for every other topic just stick to the syllabus. try doing practice essays on the 'key issues and features' bit, only once you've made summaries on each of the dot points
