The tutorial on the APA style is understandable and brief presentation. The creators of the presentation include all the most important points. A person, who had never worked with this format, will be able to make a coherent work easily and quickly. Since this presentation consists of basic information and presents only the highlights, many nuances are not included in it, but sources, where you can learn all the details, included.
This presentation seems to be complete, because its aim is not to give all the information, but only the most important and basic. For detailed information a person can read a manual or other source. Even if there are some points that one would want to add, it can go beyond the basic information. For example, in the tutorial a lot of information is about references. But there is no information about the video clips as a source or what if the article, used in your work, has no author. Of course this is not the basis, but if many pages are dedicated to references, there are questions like those.
Audio track for every slide seems to be very useful, because it is easier to remember and percept, when you read and hear the same information simultaneously. It is very good that the tutorial has samples of paper elements, because it is easier to look on the sample of work than to read about how it could be done, and when there are both variants it is the best way to achieve success in understanding. In my opinion it would be very helpful, if the tutorial gave few ideas about what are necessary points for writing a Discussion or what is Abstract and its main features.
Summing up suffice it to say that this tutorial could be very useful for a person that has no previous knowledge of using APA style. (The Basics of APA style) There could be found all basics, and if there is a need for more detailed guidance, one may refer to the official manual.
