Jeff,
I just would like to Add a little info to what everyone else here has said but I have not seen anyone mention the Bonus Workshops that go along with Each Session. Those are Advanced Lessons that coincide with the Main Workbook. You will need to Download the Bonus Workshop Book (Free). I would recommend you feel Comfortable with the Session in the Main Workbook and then go to the Bonus Workshop Book and Continue until you are fairly Comfortable with the Material in that Session before moving forward to the Next Session. I think you will find when you Advance to the Next Session it is a much Easier Transition if you were able to Complete the Material in the Bonus Workshop before Advancing, otherwise it can be a little overwhelming at times. The Bonus Workshop Workbook is Absolutely Your Friend, Utilize it ALL YOU CAN. Also be sure to Watch Both the Main Lesson Video for Each Session and when you Advance Yourself to the Bonus Workshop Workbook, there are Videos for the Bonus Workshop Sessions as well. I know this sounds like alot but do Yourself a Favor and Get Every Ounce of Learning you can from This Course. The Course was Designed to help you Become a Real Guitar Player, if you Utilize All of the Tools Steve Created, I believe you will find your Journey Much Easier. Remember....There Is NO TIME LIMIT for Completion of each Session, Main or Bonus Workshop. Take your Time and Practice until You Feel Comfortable in Moving Forward. You Don't Have to MASTER each Session but at least Feel Comfortable with the Material You Covered, I believe you will find your Journey Much More Pleasant. This is No RACE, Everybody will move along at a Different Pace......So Advance at YOUR Own Pace. What You TRULY Learn, NOBODY can Take Away from You. Should you have the Need to Take a Break from the Course, It will ALWAYS Come Back To You, typically in very short order, I say that from Experience. I am currently Back from a Break and working thru Session 4 and I Started in 2015. No Shame Here, I can Play MANY of the Songs from the Hal Leonard Easy Pop Melodies Book at Full Tempo with the Backing Track.That is WHEN You KNOW...You Have It RIGHT.....
Jeff, Take Your Time and Enjoy YOUR Journey, afterall....It Is Your Journey. I Wish You ALL The Luck and Please Come here Frequently and Interact with Us and if you have an Issue that is Troubling You, Please Tell Us About it....there will be MANY Advanced Students to Your Rescue, Including Steve Krenz.
