Answer 2

The purpose of exams that a student takes in school, college entrance exams, exams for jobs, etc. is to measure how much you know about the subjects the exam covers. In school classes, the purpose is to measure how much you have learned about the material that was taught, usually within a given time period.

Answer 3

Hmmm...it depends on what kind of exam you're referring to. Most exams are 'subject exams'. These could be in any subject in school and/or college, and these exams focus on testing your general knowledge on any given topic.

Other exams would be generalized standardized tests or specific standardized tests. The SAT and ACT are great examples of 'generalized' standardized tests. These tests focus much more on your general critical thinking skills than you knowledge on any one specific topic.

The more specific standardized tests would include tests like the LSAT (for law school) or the MCAT (for medical school). These tests do also test your critical thinking abilities, but they also dig much deeper and test your specific knowledge on certain topics needed for your career path.
