I have questions.
How detailed should my notes be at this stage?
Realistically, you don't need much more than what's in the textbook (assuming you're using Reinventing Russia, not the old crappy one). If I were you I'd be taking down the chronologies, statistics and so on from the textbook, and then reading the actual work of the historians quoted. You don't really need to add anything from their books - in my experience there's enough in the textbook so answer any question they throw at you.
Actually reading the historians' works will broaden your understanding more than you think - even just going over the chronologies again is, I would imagine, more useful than compiling massive sets of notes. The added bonus is that if you're familiar enough with their views you won't need to memorise quotes word for word - you can more or less make up the precise wording if you understand their argument well.
For Russia, I read Figes' 'A People's Tragedy' as we did the course, so about a chapter a week. Over the holidays I read Fitzpatrick's 'The Russian Revolution', which was quite short but really good for understanding historiography. I'd reccomend them both, and if you're keen you could read Pipes as well, though his views are discussed pretty well in Figes and Fitzpatrick.
So, from all that I would: not worry too much about excruciating detail in your notes - notes uploaded here are a pretty good level of complexity. Instead, spend the time reading and understanding historians' views - it'll set you apart much more than learning every single date or quote verbatim. By the end you won't even need to think about dates and events, because you will have covered them in so many sources - I think this is probably more effective than repeatedly going over your own notes.
We're not allowed to mention the historian's schools of thought, anymore, right?
As far as I know there's been no changes - you should be able to label them by school of thought. There are varying degrees of sophistication in how you do it though, for instance in this ever so slightly contrived example:
According to liberal historian Figes, the 'soviet was the worst thing evar'
is not as sophisticated as something like:
Figes' view of the revolution as 'a people's tragedy' is reflected in his statement that the 'soviet was the worst thing evar'
This obviously isn't the best example, but if you can work out ways to succinctly categorize historians without saying liberal, revisionist or soviet you'll stand out.
That probably wasn't very helpful for your SAC tomorrow, but good luck for the rest of the year!
