If you've got the money to spend (I guess it can be another part of the whole Aviation dream investment fund), the PATS course has been a big success for many pilots for giving them the edge during the Assessment 2 Stage. Have a look at the new website which will be officially launched on Monday.

Pricing is mentioned under the Qantas area in the Airlines Link. I wish this existed when I first did the testing, I'm sure it would have helped!
