AP World History Help

I’m a junior in AP World History and I’m stuck with a teacher who doesn’t teach properly. I did badly on our first unit test because most of the things she taught in class did not prepare the students for the material on the test. I’m worried she won’t prepare us enough for the AP Exam. The first unit test was all primary sources. We had analyze them and answer questions based off of them. Is that what the multiple choice portion of the AP exam is like? I feel so underprepared and it’s probably a bit early to worry about the exam but after doing so badly on the first test I’m worried for the future in this class.
