I want to change my level (Beginner to Intermediate)

Tweet

I started to learn guitar in 2002. That time i got myself admitted in a guitar learning course and learnt basic guitar like Scale, tuning, Basic Chord & Rythm. After one month i left it as i joined in a job. But i used to play guitar once a week. I have a fender- Acoustic. I know the Chord family- C Dm Em F G Am B(dim)- in other scales and uses. I can hold any major or minor chord. I can play simple solos on one/ two strings. But I can't do Other Chord uses like A7, A sus, Picking Plucking Lead in multiple string Harmonics but now i'm determined to learn the rest seriously as it is pone o my passion. I searched many sites for continuous lessons with exercises, But none is in order. But I can admit in course now. Plz suggest what should be good for me now! Thanks in advance.
