I hear that school can be pretty tough. Throwing you in water, bounceing and spinning you around. Running you on a tread mill, Lifting weights. Lots of math with no calculators, learning a lot of new words and acronyms, sometimes in differant languages and key boards. Radio operation, atmospheric pressure chambers both high and low, even temperature extremes. Learning Morse code just in case. Going up in an airplane which makes a dive so you know how weightlessness feels, some cadets barf during that. It's not a cake walk that's for sure. It seems like it's always a new learning experience.
