For a 20 hr pilot I would only start studying IFR procedures if you can answer afirmative to the following questions.
- I fuly understand the aerodynamic principals affecting all flight modes
- I fully understand airlaw and know and understand all ATC phraseology aplicable to flight training
- I know how every system in my aircraft works and have a firm grasp of all memory items for every emergency procedure in the POH
If the answer is no to these questions which based on experience is highly likely, than I would suggest your efforts be concentrated on aquiring the foundation knowledge which you will use throughout your flying life
BTW I actively discouraged my PPL students from considering any IFR procedures except at the very end of the course. I also cover up the AI and DI untill the student is 100% proficent at attitude flying by looking out the windshield. Besides what is your hurry, the best part of flying is looking down on the passing country side on a sunny calm afternoon.
