First, it is easy before it is difficult.
The biggest fear of mathematics is paranoia, which can be divided into two types: one is to see that you can't do it right away; The other is knowing that there are tigers in the mountains and leaning towards the tiger mountains. You must study first when you do the problem. If you still don't have a clear idea after five minutes, then the examinee will put the question on hold. Don't waste too much time on a problem.
Second, extreme thinking to solve problems
The general steps of extreme thinking to solve problems are:
1, try to conceive a variable related to the unknown quantity.
2. Confirm that the result of this variable through the infinite process is an unknown quantity.
3. Construct a function (sequence) and get the result with limit calculation rules or directly calculate the result with the limit position of the graph.
Third, skip answering questions.
It is common that the process of solving problems falls into a transitional link. At this time, you can admit the intermediate conclusion first, and then push it backwards to see if you can draw a conclusion. If not, it means that this road is wrong and change direction immediately; If you can reach the expected conclusion, come back and concentrate on overcoming this "stuck place".
The reasons why mathematics in college entrance examination affects the results;
First, the college entrance examination math calculation error
Computational ability is a basic ability in the college entrance examination of mathematics, but the problem reflected at present is that many candidates lack computational ability, which ultimately affects the rapid evaluation of mathematics.
In the process of marking papers, it is often seen that the method and thinking of solving problems are correct, but the mathematical calculation is wrong. Many solutions are multi-step calculation, and the calculation error in the middle step will directly lead to the corresponding error in the subsequent mathematical solution of the college entrance examination, resulting in serious loss of points.
Second, the math answer of the college entrance examination is not standardized
The math problems in the college entrance examination clearly require candidates to write written explanations, proof processes and calculus steps. Candidates must understand that doing a math problem in the college entrance examination is actually writing a math composition. Instead of writing a bunch of mathematical formulas and symbols on the test paper, we should silently show the thinking process of solving problems to the marking staff, and we must list them reasonably.
