The requirements for mathematics in driving lessons are not as high as expected. When I was a freshman, I opened two math courses, advanced math and navigation math.

Advanced mathematics is mainly calculus, which is an extension of high school curriculum, but it feels much simpler than high school curriculum, and the requirements are only a general understanding, and it will not be as professional as high school.

Navigation mathematics is mainly spherical geometry, which is also very shallow, not too deep, and will be marked during the exam.

Personally, I don't think sailing mathematics is a big obstacle. First of all, he basically applies a fixed formula, and at most he makes a fuss about the change of the formula. Most calculation problems are not a problem as long as the concept is clear. It is enough to estimate the calculation content of junior high school. Occasionally, I will give up a few big calculation questions, because each exam will not exceed 2 questions.

Failing math in high school is not afraid of being laughed at, but the third mate takes the exam as usual. The key is English, which is the point.

If it is a 2-year training class, you may not be given a math class alone. This is not the content of textual research. The training class can be saved.
