for lvl one, my gut feeling is that it should be fine since most of the test points are basic and the coverage wont change a lot year to year.
for lvl 2 and 3, esp lvl 2, the format has changes from MCQ-Essey in 2004 to All-MCQ in 2005, so it is not sure whether the old notes are still sufficient. My own opinion is that I dun care. Tell yourelf that you are studying Finance but not JUST an EXAM, you will understand what I mean. If my finance knowledge is not strong enough to pass lvl 2, so fail me and I have no complaints.
