Hi Hazell, I would forget the one week intensive course untill you have read each of the Air Pilots Manuals and have a copy of LASORs.
As each of these manuals is about 440 pages I found it difficult to read them from cover to cover in less than 10 days each. They also have example questions, which if you know the subject adequately, you should be able to answer 80-100% correctly.
If you get really interested in one particular subject you can become side-tracked... I for instance made sketches of all cloud types and their heights. I also studied Navigation maybe too deeply, but now I know how to use a sextant and a chronometer to find Lattitude and Longitude, thanks to some very old Navigation Handbooks.
