For those who have done the course...

You have finished the core program (first 13 months) and after that lets say atleast 6 months have passed. Do you feel your strenght is still the same (do you still do the same as when you finished the first 13 months) or does it gradually goes downhill again. If it goes downhill or stays the same: What is the reason for this? No more intensive chess study? Real life sticking up his ugly butt again? ...

My strength has remained increased, but because I have not repeated the course, some of it disappears.

My biggest problem is memorising openings and I think that will always be my greatest weakness.
