Ape tutor selection education edition and Beijing Normal University edition are both good. People's Education Edition has more contents and more details, but it is more difficult to finish because of its many contents. The teacher will speed up the lecture and speak very fast, which will lead to students' incomprehension. The edition of Beijing Normal University is slightly different, with less content, but the key knowledge and important knowledge are still there, that is to say, the basic content is there.
