I left Australia mostly to avoid flight planning. The ATP was study-able in about 5 days, with the study software saying, "if this question asks about a papi, the answer is xx, if this question asks about a mtow out of x airport, the answer is y.
The software guarantees money back if you get less than 80%, some people were so dialled in on the question bank, and poor, that they deliberately got some wrong so they'd get 79%
