Compare & contrast: American SAT and Chinese Gaokao

Many American high school students take an SAT to determine what college the are eligible to apply to. Many Chinese students take a test called a Gaokao to see if they can even get into college. For American students, if you happen to score low on the SAT, you will still be able to apply to a community college and be accepted. Students in China who score low on the Gaokao, will not be able to get into any college.
To American students, a four hour test seems quite long. Imagine taking a test that lasts 9 hours. This is exactly what the students in China do for the Gaokao.

The college entrance tests in China are taken so seriously that if a student does not do well on it and then is not accepted in to college, they are shamed by their families. An example of this is a student failing the Gaokao and his mother did not speak a word to him for weeks. This is not the case for most families in America. If an American student fails the SAT, they just retake it for a better score. Parents generally are not too upset.
The Gaokao includes several sections. These include a section on Chinese, English and mathematics. On the SAT, students are tested on American reading and writing and mathematics.
A sample question from a SAT might be; in triangle ABC, the length of line BC is 2, the length of side AC is 12. What could be the length of line AB?
 A sample question on the Gaokao is; in a square with sides a, b, c and d, the intersection of lines AC and BD are O, and e is the midpoint of section OD. AE is the extended line, which intersects with line CD at F. If the length of line AC is A, and the length of line BD is B, then what is the length of line AF?

Needing to do well on the Gaokao is a necessity for students in China. This puts China on the forefront of technology and education because Chinese students take education very seriously.
