Hola Amigos
I am going to take the Fund.I exam in a few weeks...I am feeling pretty good about things, except the multitude of views that need to be memorized.
Im going to make a list of them, if I can find enough paper, and commit them to memory.
Does anyone out there have a better idea? How did you remember all those dynamic / dictionary views? What a pain !
