I have been sitting here reading this thread (and others) with a little smile on my face, heard it all before.
The 25 hours is the MINIMUM hours needed, and what percentage of students with the minimum are ready for their GST? very few considering time, weather, wives, girlfriend, kids,work etc.
Most schools sell the dream of 25 hours, wake up and smell the coffee, it takes as long as your circumstances and ability.
Best of luck, keep at it, and gentle breezes.
