School tests.
 Knowledge test. There are many exams that test your knowledge in different subjects in order to find your level of proficiency in certain disciplines, for instance:
• A math test measures your ability to solve problems;
• A history test finds your awareness with some historical facts;
• An English test might ask you to show grammar and lexical skills.
Tests of aptitude. These tests do not check what you have learned at school, aptitude tests aim to measure how well you learn or understand things. For example, an aptitude test might show that you’re natural math genius and should be placed in an advanced class. It can also tell the teacher that somebody needs extra classes or so.
An aptitude test might ask you to:
• solve problems that rely on your basic understanding of numbers and math.
• render or retell the paragraph you have just read.
• test your reasoning or ability to understand words and ideas.
Classroom tests. These are tests given by teachers to check what you have learned during the classes. They also determine your grade for the class.
Standardized tests. It means that the test takers answer all the same question, pass some concrete topic. These tests are usually identical for all students in a school district, county, state, or even the whole country. Government officials decide that there are certain facts or skills that every single student should know, and write a test that covers this material. For example, your state might feel that every student your age must know that World War II ended in 1945, or that the radius of a circle is equal to half the diameter. Because of this, these questions will probably appear on a standardized test, and your teacher will probably make sure to cover these things so you’re prepared.
