Well im not new to guitar, but right now i know the penatonic scale, up and down the neck, and thats about it. any experianced players have any ideas on how i should go about learning the rest of my scales?

I really enjoyed the modes although in most books this is the last step, but you can take a look at them and decide for yourself.
Also the scales right here on this stie are right on except the A minor third inversion it has a mistake in it see if you can find it.rather it has an ommision

i would start with major and natural minor scales and learn thoes in a place or two and get those to be second nature before moving on. Make to to learn teh relative minor rule. basically for example e minor and g major scales are composed of all the same notes. then i would move on to modes.
