In mathematics, the first choice is generally complex number, followed by function transformation, trigonometry, probability and so on. Every year, there are new tricks that need to be mastered. The last question of conic section is mainly to seek eccentricity. Give three points before filling in the blanks, and the fourth question changes every year, which is more difficult. The big topics are trigonometric function transformation, simple probability, solid geometry, derivative, conic curve and functional inequality in turn. Comprehensive, multiple-choice questions are scattered, but genetics, redox, ions and gases are tested almost every year. There is one experiment in physical mechanics and one experiment in electricity, with three basic viewpoints of mechanics 16, celestial bodies and electricity 18 and electromagnetism 2 1 min. Chemical redox, elements and compounds, organic examination, a random question; Biological experiments, genetics, compulsory exams, and others will get extra points. It's too rough here to list the problems. Sorry, I can't write them down.
