I want to ask, is there a difference in the scope between AP calculus AB and BC? How difficult is it? Does it help if you do AB exercises with BC?

Short answer:

1, BC is a little more difficult than AB, and BC takes one more function series;

2, doing the AB question is of course helpful for the BC test, at least the basic score has been obtained, and it is already nine times out of ten;

3. However, after finishing AB, it is best to find a solution to the series problem of BC, not limited to AP and GP.

Where AP = arithmetic progression = arithmetic progression, arithmetic progression,

GP = geometric series = geometric series, geometric series.

4, in addition to the weakness of domestic students in calculus, pay attention to two aspects:

First, domestic students' graphic sketch ability is very poor;

Second, GC must be familiar with it, very familiar with it, otherwise it will suffer a big loss.

In China, even high school math teachers are unfamiliar with GC, far less than high school students in Britain and America.
