Yes,just keep plugging away at your acoustic.Its normal for your fingers to get sore,and to slur your notes whether your playing chords or scales.Open C chord still gets me at times.Thats why I practice so much lately.If its any comfort,when you go to electric guitar it will be so much easier for you.I just try to remember all the shapes to chords,and basic patterns to scales.I learn all the new stuff on my acoustic,then go to my Les Paul.Hope that helps.
