As a student, we've been taught to turn in our work, do what the teacher says, and that's it. For AP, those rules still apply, however, it's more than just that. In any AP class, throughout the year, students form a rapport with the teacher; one that helps the student succeed in that class. It differs because, hopefully, the teacher should be working with the student towards success, not doling out work and letting all the students completely sink-or-swim.
So yes, AP menas college, which means the 'sink-or-swim' theory applies, but since it still is highschool, the teacher should be trying to help every student reach success. However, this is not all on the teacher. As a student, one should be willing to work with the teacher to reach success in that class. What does that entail? Well..
As an AP student trying to succeed you should be willing to take the necessary steps, such as:
1)Developing a GOOD rapport with your teacher-Being on bad terms with the teacher would create tension and that would make it harder to concentrate or be motivated to work hard.
2)Stopping in for help-Most teachers will take into account the effort you make by stopping by, and may give you useful hints and tricks to do well in that cerrtain class.
3)Taking critism into account-If you get a 3 on your first essay, don't pout. Ask why and try to remember that the teachers aren't being mean, they're only challenging you, which is good, since that's the reason you should be in AP. <-To challenge yourself.
In conclusion, working for your AP teacher, and only doing the work will get your work to be only so good. Working with the teacher, asking for help, and other such things is what will help your good work to be great.
