Another thought: You might want to learn your scales, etc. in Circle-of-Fifths order rather than chromatic order. They really make much, much more sense learned in the right order, because as you progress around the circle of fifths, you add just one sharp or one flat to the scale you had before.

So you would start with C major, then learn G major (one sharp) and F major (1 flat), then learn D major (two sharps) and Bb major (2 flats), etc. The order for minor scales would be A minor (no sharps or flats), E minor (one sharp) and D minor (one flat), etc.

If you google for "circle of fifths" you will find many diagrams and explanations. It may seem a bit dry & obscure at first, but it is one of those things that, once you know it, you find yourself using it all the time. Really, I think it is the single most useful bit of theory I have ever learned.
