1. Fill in all candidates' information and check whether there are any problems in the test paper.

2. Adjust your mood and enter the examination state as soon as possible. You can answer simple choices or fill-in-the-blank questions that can be concluded at a glance (once solved, your confidence will be doubled and your mood will be stable immediately).

3. Questions that can't be answered immediately can be roughly divided into two categories: A and B when browsing: A refers to familiar and easy-to-use questions; Class b refers to the questions that are unfamiliar and have difficulty in feeling, so as to be aware of them.

Scoring skill

1, the last problem of conic curve is often too complicated to get together, so k can't be calculated. At this time, k can be calculated by special value method. The process is simultaneous first, then calculate δ, and list the expressions of the solutions needed by the topic with David's lower theorem.

2. If there is a cone volume and surface area in the multiple-choice question, the answer is to look directly at the option area and find the small one with a difference of 2 times and the small one with a difference of 3 times is the answer.
