-First of all, AL (China Hong Kong Advanced Level Examination) won't get 26 points, but CE (China Hong Kong Certificate of Education Examination), right? -M 1 and M2 are calculus and statistics and algebra and calculus respectively, and M 1 is closer to the previous department of advanced supplementary mathematics and statistics (as m & amp； S), M2 is closer to the level of additional mathematics and a small amount of pure mathematics in NMET. -M2 is more difficult and abstract. -Calculus is divided into "differential" and "integral". Differential is a set of theories about the rate of change, such as calculating the slope of a point on a curve; Integral is usually used to calculate area and volume. If y = (x-2)(x+3), can you calculate the slope of this point when x = 3? This is one of the applications of calculus. Of course, the real thing is not that simple.

00 1 except that M 1 is not as easy to get a high score as expected, it has basically told the truth. It's not difficult to learn.

But it's hard to become a professional.
