Hey, there! Congrats on making it through the fundamentals courses! Those courses are very much for beginners. As a result they only go far enough into scales & patterns to introduce the idea & get you playing basic scale patterns.

And these tutorials cover major & minor scale patterns across the fretboard in detail.

But keep in mind that those are more of an intermediate skill. It might be more beneficial for you to start to work on one of the style courses (blues, country or rock) & learn some songs. That way you will also start to build your skill ina way that is integrated with other aspects of music & apply them toward learning a repertoire of music to play.

[quote=lorenzo.cerolini][br] Or should I just memorize the different scale patterns? So far I've been working them out by learning the position of the notes on the neck, instead of learning specific patterns.[br]

After you learn those 3 types of patterns, you've got the basic idea of what scale patterns are possible.

Hope that helps! Please ask more if necessary. Best of success!
