There are 27 PPts included in this collection, addressing three major topics for Paper II in IB History. These PPTs cover most of the school year along with the Paper I PPTs; therefore, there is enough year II (20th century world history) content here to cover the exams. In addition to content covered there is prompt practice throughout. Lastly, there is reference to numerous historians for additional support. May 2015 exams I had a 97% pass rate!
