Play all 12 scales moving chromatically, not around the cycle of fifths. Once you've played all 12 scales keep going up through the next octave. Like scales, you need to set a target tempo for each etude before you start practicing. Some students find etude books boring, seeing long lines of repetive patterns. It's important for you to get past this point of view, and instead look at each etude as being an excecise with a specific purpose.
Some etudes emphasize certain techniques, or certain keys, or specific styles, etc.
Identify the purpose of each etude and play with the goal of meeting this purpose perfectly every time. An etude is not just something you play, it's a challenge. For an added bonus, whenever you play a piece that has a famous excerpt in it, copy it down on a piece of manuscript paper and throw these into your etude book to practice between etudes. It's good to keep practicing these excerpts beacuse they are often used in auditions for conservatories and symphonies. As a serious musician, you need to have a repertoire of solos and concertos that you can play very well.
