I think the right answer is 'it depends'.
For myself, I had already purchased my own gear (including drysuit) and was at the point where my buoyancy with the drysuit was 'acceptable'. By no means good, but I was able to hold safety stops and had decent trim ... for someone new to diving and new to a drysuit. I went into the AOW course with 12 dives, 5 of which were drysuit dives, all in the previous month. Unfortunately I was the MOST experienced person in my class. I found the AOW too easy and wanted to be more challenged (we did PPB, deep, nav, wreck and night). Though I did enjoy the Nav component.
Just my $0.02.
