Today's Human Geo

Tomorrow, we have an important test, it worth 100 scores, which means if I get a great score in this test, I can totally increase my grades in Human Geography. Last time, I get a terrible score, because I didn't work very hard before. But this time, I feel still very nervous, I lost my confident after that time. I just want to say I will try my best. Tomorrow is also Friday, it's the best news today. This time, we talked about total fertility rate, which means how many kids per woman. And also about the increase or decrease population. Of the whole world, every family should get 2.1 kids. Because at this time, the crude death rate is less than crude birth rate. So that's it. God bless me, let me get a great score tomorrow.
