Kant "so confused"

After reading parts of the book, I still really do not know what its about. I just found it very confusing to read and by far the hardest material yet. I enjoyed reading about the math section on how pure math is possible. You can tell by just this book that he is all about the sciences. I dont think that when it comes down to the science section that there could be any right or wrong answer, with how he is trying to prove metaphysics.
