If i could change one thing in the world I would change my country's education system. To emphasize practice over theory and the study subjects but also practical importance. Reduce class time for students to have time to read books. The last one was not very sure. The test should not be too difficult. Do not look at others who study or have graduated college, many students are not even finishing it with a great future. It will be good to everyone but himself survived knowledge is meaningless. States that if I do what I say education must develop it.
