If you've tried to learn Illustrator or Photoshop from books, or from sites that don't offer instructor-interaction, you might enjoy my classes from Ed2go. I've been teaching them with great success since 1999. I am online with these courses five days a week to answer questions and offer help. I have experienced teach assistants who typically work all 356 days of the year!
ed2go classes are very interesting--they consist of 12 lessons, released 2 per work for 6 weeks of an 8-week session. A new session starts every month. You can work at your own rate and ask questions whenever you get stuck. During the work week, you'll get a response by the end of the next day (or sooner). I've helped thousands of students with these classes and if you want a general introduction to Photoshop or Illustrator, you'll learn a lot.
I am currently teaching both Introduction to Photoshop and Intermediate Photoshop classes for Photoshop CS5, CS6, and CC. Click on a link below for more information.
The Introduction to Illustrator CS6 class the only one on Illustrator but I give added value for CC students and can give you downloads customized to CS4 and CS5 as well.
