You can always use a good text book. The ACA Learn books are my recommendation because you can log the books purchase at peachpit.com to access the e-book complete with videos!!! In addition the authors are actually teachers. The books are written so that students will be prepared to pass the ACA Certification tests which is an added bonus. You will want to make sure as you look at these books to get the second edition that just came out. There is one for each ACA Exam!
Today this curriculum is setup to organize a year or semester course to help students learn in these digital careers. Make sure you are signed into the Adobe Education Exchange (edex.adobe.com).
