There's alot of ways to use your finger's ,for the,first position of the A Chord at the second fret.
I use the the second finger on the D String,third finger,
on the G string,Pinky on the B string for making up the,
A chord plus the open A string.
I find this better for my style of playing plus it,
works better for some students when first starting out.
Try practicing A to E A to E ect.
