After taking the QGIS Beginner All-in-One Starter Pack (Theory/Practical), I liked it so much that I decided to enroll in this course as well. Compared to the All-in-One course, there is some overlap in the background knowledge needed for the course (GIS concepts) and basic vector data handling (layer joins). However, it was useful to be able to learn new content by going deeper into vector visualization. Additionally, learning the layout function using composition was the second biggest takeaway. So even though there was some overlap with the All-in-One content, it made sense as background knowledge for people taking only this course, and the new content specific to this course - advanced vector visualization and layout composition functions - was useful. The teaching method doesn't just stop at explaining concepts, but includes hands-on practice throughout and ends with practical examples, spending plenty of time to ensure I could fully understand and make it my own.
