But they're not 141. How could you have all that with only 235 hours?
Also, regarding places teaching you to teach. It doesn't really happen that way. The only way you become a skilled instructor is by going out there and doing it. Remember, the backbone of instructing is the gradual transfer of controls to the student. As long as you're safe in the right seat and know what's expected of all the maneuvers, you teach yourself how to teach by experiencing all the different personalities.
Know the Fundamentals of Instruction! Not necessarily the learning is meaningful, purposeful, etc... crap. It's the defense mechanisms that you'll have to deal with A LOT. How you handle all that can make or break you.
Also of importance, the building block concept, you can't force feed a student info.
Other than that be a great stick in the right seat and sharp on the radio and you're good to go! Good luck.
Oh yeah, I have to edit this in, it is unlikely that you'll use the CFII and MEI very much off the bat. If you want to save some money and really focus on training private pilots well, you may want to consider just getting the CFI and hold off on the II and MEI.
