In fact, they have all been tested. College entrance examination questions, especially multiple-choice questions, are mixed with the learning content, and each part must be mastered before you can do the questions. If I say which part is less, there are only three required exams. I am a liberal arts student, and there are six major questions in the college entrance examination mathematics. General problems are series, trigonometric function, solid geometry, probability (or linear regression), conic curve and derivative problems. There is also a multiple choice question (parametric equation or inequality).
