AP Chemistry
AP stands for Advanced Placement, which is the university preparatory course. The AP exam was held by the College Board in 1955 to give high school students access to college courses and to complete some of them ahead of schedule if they have the ability to do so. There are 22 categories, including 37 different courses.
As a basic course of science, AP Chemistry requires students to learn the knowledge that freshmen need to master in the first term like basic chemical knowledge, chemical principles and experimental operation.
The Contents of AP Chemistry Include :
- Material structure
- Material state
- Chemical reaction
- Chemical experiment
From the knowledge content, we can see that chemistry is a partial science course, so if the students have a particularly good memory, it is easy to get high marks.
Also chemistry is a first-year basic course for Science (science) and engineering majors, that is to say, chemistry is a compulsory course for all science students and will affect the choice of majors in the future.
AP Chemistry Course Four-points Rate
The probability of getting a score of 4 or more in AP chemistry is 26%, which means that 1/4 of students have a chance to convert AP chemistry into college credits.
