Augmented

Augmented is a chord not a scale. Possibly you mean whole tone as you missed that from your list

6th mode of Harmonic minor

Why this ?

That's a lot to concentrate on, I would recommend you learn fewer scales but learn them more thoroughly, and in more keys per day.

Also leave time for work on tone, repertoire, transcribing, listening and improvisation (if you want to learn impro)

The augmented scale has the half step/minor third or minor third/half step structure;

Great, I learn something every minute.

However I think the whole tone scale is more useful to begin with.
