A Mixolydian b2 b6 has one avoid note the 4th degree. This mode can be used in much the same way as a Mixolydian b6 Mode so experiment with the mode in the same ways.
After you play the mode you are working on you should then improvise with it over a jam track. Learning the names and degrees of each note with a mode is very important to your overall understanding of modes and eventually will allow you to organize them efficiently in your mind. It is of utmost importance to improvise with these modes each day so that you learn the sound of the scale and begin to see melodic and chordal applications. Use a jam track or make up your own with a looper. Remember to first start with a small section of the scale to improvise with. Keep in mind that it takes time to improvise well so don't expect too much too soon.
Chords should take up 20% of your practice time and should be practiced in the follow ways.
1. Use a chord book that gives you common voicings and chord progressions to apply the voicings you are learning. You should learn all barre form chords in all key so use a cycle 5 progression to learn each chord. The most basic barre chords have their root on either the low A or E string. If you were playing a major barre chord on C with the root on the A string you should move this chord through cycle 5 so that you know it in all keys. For example play the C barre chord at the 3 fret of the A string then move it to the F barre chord at the 8th fret. Continue on by moving the same major barre chord to Bb and the 1st fret. You should continue it thorough this cycle 5 movement:
2. I would first start out just learning all your barre chords in all keys for a few weeks. It is important to start applying chords to chord progressions. If you don't do this you will never remember all the chords you learn and even if you did remember the chords you would know how to use them. For applying open chords (chords with open strings that are found within the first few frets of the guitar) I would use either

Ear Training should be practiced one hour a day and should be not be included in your practice time unless you are practicing more than one hour a day. I would practice ear training any time throughout the day that you have some down time. Common times that students use for ear training are commuting to work, lunch breaks, before going to bed and any time you know you will be spending time waiting for something. Remember that even a few minutes will make a major difference over time. I recommend a specific type of ear training that will improve your recognition of how all 12 notes sound within a key center. This is NOT interval training. The ear training method I recommend focuses on memorizing the sound of all 12 notes in a key center. I recommend using one book to identify pitches and one to develop your ability to produce the sounds of these notes from within yourself through singing. The exercises found in the books below use audio CDs to help you memorize the sound of each pitch. The books will explain the method in great detail. You should practice ear training in short multiple segments each day. I usually recommend practicing ear training 10 times a day for 5 to 10 minutes.
