Compasses are recommended for college entrance examination. Although compasses may not be needed, candidates should prepare compasses in case they are needed for drawing. Candidates need to prepare corresponding test tools and articles that meet the requirements in advance.

Candidates need to prepare test equipment, such as 0.5mm black pen, 2B pencil, pencil sharpener, ruler, compass, triangle, eraser, etc. It is best to pack it in a transparent stationery bag. Candidates should leave ahead of time before going to the test center and reserve enough time to prevent the exam from being delayed for some reason.

Matters needing attention in college entrance examination mathematics

1, pay attention to solving the trajectory equation, and consider three kinds of curves (ellipse, hyperbola and parabola). Ellipse is the most frequently tested, and the methods include direct method, definition method, intersection method, parameter method and undetermined coefficient method.

2. Pay attention to whether to find the trajectory or trajectory equation.

3, pay attention to the straight line (method 1 points have slope, no slope; Method 2: Let x=my+b (when the slope is not zero and the midpoint of the chord is known, the point difference method is often used), and pay attention to the discriminant and Vieta theorem; Pay attention to the chord length formula and the range of independent variables.

4. It is better to find out the problem of setting value through special positioning first, which saves time.
