For a long time. I find that my study efficiency is very low. I spend a lot of time taking notes or Listening lectures. Give myself lots of tasks. But finally, I can't absorb knowledge, and I can't complete the tasks which I give myself. So，I hope I can learn how to learn efficiency. How to make my own study plan. Deal with the conflict between study and job. Know our brain structure. When I finish the course. I will use the knowledge to study more course on Coursera. Handle the daily work and services. Also, I will help my family and friends. Teaching them how to use our brian to get a efficient study. Thanks for evaluating my homework.
