:)... Why are you learning the major scales sepratly? They're exactly the same just moved up and down the fret board accordingly!! Do you understand what I'm saying? Basically Cmaj can be played from open strings to the 12 fret, if you want to play Dmaj you just move Cmaj up to start from 2 to 14 (moved up 1step ie the different between the notes), fret 0 (the open strings) and 1 are not a problem as the pattern repeats it self, so they would have the same pattern as frets 12 and 13 respectivly...
Hope this save you time...
