so, today i was reading my anthroplogy book and I'm three chapters behind and we have a test a week from friday over five chapters. So my reading experience today wasn't very good because I was distracted too easily. I was in the learning center and my phone kept going off and I was not able to focus on the reading task I set for myself before I went home. I have tried to read with headphones on before, but that doesn't allow me to learn the information. Why do I have this problem???
