Quick Links to training courses:
You can get individual apps, for example InDesign as a stand-alone app, or you can get the whole suite of Apps. If you want more than one app it is usually cheaper to get the whole suite called Adobe CC (Creative Cloud).
There are also very good deals to be had for students.
Below are links to the Adobe website to view the options. (If you don’t see the link turn AdBlocker off on this page.)
