Po,

This advice falls squarely under the easier said than done banner, however:

Take this as a learning experience- nothing more, nothing less

I agree that you shouldn't pay for a jet transition course; none of my pilot friends did that. I cannot stress how much of a resourse Microsoft Flight Sim is. Get it and use it like you would your girl/guy if she/he were a supermodel. Fly something faster than what you are currently flying- I'd recommend the King Air and the 737. If you become proficient at hand flying both in maneuvers, approaches and holds in IMC, all future evals should go much better. Take it from me, I am speaking from 1st hand knowledge here and I have both turbo-prop and jet 121 experience. I have more time on Flight Sim than total time in my logbook. It will build your scan and make you flying that much better, trust me.
