The situation of the national college entrance examination is similar. I've read Liaoning papers for several years, mainly because of the compulsory examination. Solving problems mainly examines trigonometric function, sequence, probability, solid geometry, derivative and function, analytic geometry, and the required content is 12345. The above contents are compulsory. The college entrance examination generally has three multiple-choice questions, namely, geometric choice, inequality, parametric equation and polar coordinate equation. Any of these three questions is necessary. The effect is very good, and passing or 100 is no problem at all. I hope my advice can help you.
