Hi Ryan
Sounds like you are making good progress .... and the fact that you are recognising your mistakes is the first step to fixing them - I wish more of my students had the same outlook
Common mistake is to focus on instruments - the most accurate indication of flight attitude is outside the aircraft (any guesses what it might be)
Instruments lag pilot input - if I see a student focussing inside I will cover the instruments up - it always surprises them how much better they do when they have to look outside !!
Just to add a few comments on climbing and descending - airspeed is the worst culprite in terms of lag - student regularly chase the airspeed - remember Power + attitude = Performance - at a given power for example climb power - if you always set the same attitude - you will always (almost) get the same performance in terms of airspeed and ROC
Back to the turns .... as already suggested - get your instructor to demo a left and right 30 AOB turn - ask him to hold the turn until you have satisfied your self you are happy with the picture out front .... ie where the nose is relative to the horizon for each turn (note it will be different for right and left turn if side by side seating) -
If you put the nose in the same position (with given power setting) you will always complete a 30 AOB level turn - guaranteed !!!
It is also common to overcontrol in turn - in your case pitch - again just match the picture outside with the mental image - once in the turn make small adjustments - just a few cms is enough (depending on a/c) to maintain the turn - do occasionaly check instruments - to confirm height and when to turn out - but 95% out max 5% in
Rudder has been mentioned - with a little practice you will automatically apply the correct amount of rudder in a turn, or when changing power setting or speed - again this is just practice
Good luck ...... and in the unlikely event your instructor does kick you out - your welcome to come flying with me any time
