Intensity - you may not necessarily find the online course overly challenging, but there is a lot of content to cover. We recommend processing & practicing the content of the online course on your own. Completing everything should give you a general idea of what the Academy will cover, as well as get you familiar with understanding the logics of code.
Motivation - the introduction should be used to gauge if this is something you really want to do. If you are really serious about pursuing a career in programming, then you shouldn't have a problem completing it, regardless of the effort you need to put in to finish it.
