I am curious to know more about how you work with your assignments, Dima.
This is not an X pieces for one semester thing. I may be mistaken, but it seems to me more like a deliberate drill to:
1) force you to get quality work done within certain very rigid time limits
2) show them (and yourself) that you really love your Art, show them that you respect them and that you are ready to work up to the quality they are expecting from you, and in general: that you are ready to make sacrifices to prove that this is your calling. You don't talk much; you simply do.
The first day (when the work is assigned), I do everything to "prime" the assigned repertoire. This means getting it fluent and comfortable everywhere. I do not stop until this is accomplished, however long it takes.
Reason: before I can enjoy my artistic tea, so to speak, I *have to* boil the water and I cannot afford to delay that process (=take the kettle off the stove a couple of times before the water boils), otherwise my artistic tea won't have enough time to "brew" within the set time limit (a week or so for very demanding works I may never have seen or heard in my life). This takes as long as it takes, but I have to do that the very first day to feel psychologically comfortable about my preparation.
When this is accomplished, I can shift back to lower gear for the rest of the week to work on what I think are the artistic points, but such that I don't ingrain a set "interpretation". On the contrary: I will have to be ready to react to any weird requirement on the spot within that repertoire, so automated "interpretations" pretty much work against you.
BUT...! I also have to:
1) prepare repertoire for ensemble playing
2) broaden my repertoire with stuff that may be expected some time in the future
so I have to sightread a lot, initially not one of my strongest skills. I have improved a lot, though, by deliberately putting my books upside down and read like that for fun. It helps you cope with fear, uncertainty and doubt.

P.S.: I guess I am just not talented enough for Mr. Podesta's 2x2-hours-a-day regimen because I am sure that if I follow that, I'll get flunked.

Mr. PodestaI am not giving advice to the OP. Just telling her what some students have to go through to survive in a system they did not invent themselves. I suspect that the renowned Schools in the US require the same from their students.
