These links help me a lot to understand about Present Perfect Continuous (PPC), and the different between these and Present Perfect Simple(PPS). The explanations and the exercises are so easy to understand but sometimes I was confused about when use PPC or PPS, then at the exercise I was wrong. But the pages show me my error and tell me the good answer.
