As others have pointed out and I feel compelled to echo to drive the point home, learning scale fingerings is absolutely worthless without learning to relate the scale to chords and progressions. We can all pick up the Guitar Grimoire and learn a Himalayan minor scale, but then what do we do with it?
Take, for instance, the Lydian Dominant scale. Very cool fingering pattern. What is it though? It has "dominant" in the title, so it must have a b7, and we all know Lydian means a raised 4th (#11th). Combine those two and you have a very hip scale. But it will only sound hip if it is used properly. Would it sound hip to play an A Lydian Dominant over an Am chord? Ugh, I don't think so. First, the lowered third of the chord would create too much tension against the natural third in the scale. But, if you instead played a D Lydian Dominant atop an Am chord, then you're making magic.
What other, very popular dominant scale are we familiar with? Mixolydian. What's the difference between the Mixolydian and the Lydian Dominant? The raised fourth. Can we substitute the two scales? Definitely, as long as the underlying chord does not have a chord tone clashing with the raised fourth in the scale. But, playing over a simple dominant chord will not provide any clashing tones and you'll sound pretty cool and outside at times.
If you want to get jazzy, where can you use the Lydian Dominant scale? Make use of its raised fourth (or flatted fifth - the tritone) in tritone substitions of the ii-V-I progressions and you can really go places. Take Bb as our tonic and the progression would read Cm-F7-Bb. Add some colorful tones and we can come up with something like Cm11-F7alt-Bbmaj7. The tritone substitution can be used for the V chord - the tritone of F is B; so, use a Cm11-B7#11-Bbmaj7 progression and use B Lydian Dominant in the second measure and you'll sound like a serious jazz hound.
I again echo - do not merely learn fingerings of scales. That is a worthless exercise. Learn how to apply those scales and what makes each scale distinct and unique in the world. Then learn when to whip them out in an improv session and you'll turn heads quickly.
