Multiple choice questions are generally the first type, the second type is triangle, complex number and set, the latter two types are most likely conic curve and derivative, and there must be a program block diagram in the middle, as well as series and linear programming multiple choice questions. If you do more simulation questions, you will find that the first one is likely to be a triangle or a series, the second one is mostly probability statistics, the third one is most likely to be solid geometry, and the fourth one is likely to be a conic curve.
