That’s plenty of time to get yourself set up. Get the writtens done. You’ll thank the mentors later, when you’re flying and your classmates are grounded studying for a particular written. Get as many modules on the Private part of the intranet done. There are two sets (ASA and King’s). Get them both done. Study the Cessna/Piper supplement and answer all the questions in the back of the respective supplement by your start date. It will teach you about speeds, key training concepts, systems, etc. While you’re not required to be able to draw out aircraft systems in excruciating detail for the private phase, you are required to know what the various systems do, how they are set up, and what to do if something fails in flight (e.g. alternator failure in flight, how to detect it, what to do, what are the effects of losing your main battery, etc). When the bundle arrives, start reading the chapters in the PHAK and AFH that are associated with the intranet modules you’re watching. Take your FAR/AIM and become best friends with it. There’s a section in the front that breaks down regulations by applicability to each specific license and rating. Highlight and tab the Private ones for easy reference. Also, I recommend a book called Everything Explained for the Professional Pilot. It’s $60 but well worth it and will help you study and instruct in the future. Download LiveATC and start listening to various frequencies at your training airport to get an idea of how things operate from day to day there.
In 9 months you should be well set to breeze through the first stages of the program.
As Adam said, it is a very time consuming program. You’re frequently at the training center by 6, and sometimes don’t leave till 6-7 pm. Get home, eat, study, do navlogs (bleh!), sleep, wash rinse repeat… Monday through Friday and some Saturdays. Best of luck!
