The more you learn the more you realize how little you know
As I mentioned a while back I am learning Amud Yomi with tests. We just had a hard test on 1 perek (about 15 blatt), which really required you to know the perek. I reviewed a lot and thankfully did well on the tests and I feel that I really know the perek.
However, before I get a swelled head, I realize that this is a drop in the bucket. Right now I know 1 perek, I really need to know all of Shas at least like this. When I think of my Rebbe, RHS, he can do this on any Maseches in Shas and much more. He can tell you all the shitos of the Rishonim, Acharonim, Rambam, Shulchan Aruch etc. on everything.
After learning 1 perek and trying to keep all the information in my head it is mind boggling to me that someone could have all of Shas, Rishonim, and Acharonim like that. However, that is my goal, when we finish this Masechta we are going to have a test on the whole masechta and I hope that I can do as well on that as I did on the perek test and remember it. After that, we will move on to the next masechta etc. until we finish Shas. This is a very long term plan but doable.
There is a story about the Gra that someone came to him and said that he had just learned a given masechta. the Gra then asked him how many disputes are there in the maseches between Abaye and Rava, the person was dumbfounded and couldn't answer off the top of his head. The Gra then proceeded to list off all the Amoraim and Tannaim mentioned in the mesechta and what they argued about etc. right then and there without having to think for a second. That is bekius.
I really recommend this kind of program for everyone, it forces you to do Chazara and the tests give you a good sense of where you are. It gives every person a realistic opportunity to learn Shas and actually know it.
