AP English Language and Composition for Junior

My daughter has been on the AP Science track with AP Chem and Math. She was recommended this year for AP English Language and Composition for her junior year. Usually, only the students from the honors track will go on to AP courses. I am wondering in anyone can give me any insight as to what gaps she might have going from mainstream English to AP? How difficult is AP English Language and Composition?

First off, let me preface this by saying the difficulty of an AP class ranges from person to person.

However, from my experience, AP Comp kinda forces you to be more professional. It helped me balance creativity (with my overactive imagination) and professionalism.

Although, sometimes, I did hate it. My teacher gave me a B on an essay (also prepare for one essay a week) and I asked her why not an A. She responded by saying there was nothing wrong with my essay. She just thought it was not A material.

And did I mention you have to do an essay a week?

Thanks. That was kind of what I was thinking in that it would force her to be a better writer.

And from teacher to teacher. That said, I felt it was one of my most valuable HS classes. It teaches you how to be a better writer, which is not only a life skill, but proved invaluable when writing essays for college apps.

I am going from English regular to AP language and composition as well. Its a lot
