You can have
this, which is the workbook I used for AoS1
You obviously won't have the readings booklet it's based on but most of the questions don't require them.
Renaissance will always have a special place in my heart, I'll get around to uploading my notes eventually
I know there's probably a lot more about both Florence and Venice to be said, but I'm doing this in the context of Unit 3, AoS 1 pretty much, so there's not a lot of delving in, just more an overview of the republics. That said, I like harsh critiques.
You don't have to provide essay level detail (and in fact you shouldn't for these questions). Before you read my feedback, I'd like to point out that I'm not a Ren expert and I sure as hell don't tutor it (although I love it to death). My major problem with the response was that it didn't really address the question properly. It said to explain the characteristics of a Republican government, but you only really did civic participation (or lack thereof). You might still have been awarded a high mark, I have no idea. I got the feeling that your response would have been better suited for a more discussion based question but ask your teacher about the ideal formats.
My response would have been a lot more simplistic: I would have listed 5 elements that comprised a republic and provided a point of evidence for each. So something like:
checks and balances on power - Florentine "bag" for selection of offices
upper class citizens only - venetian golden book
prevent corruption and permanent office - Doge and the idiotic selection process (perhaps idiotic wouldn't be a good term to use though

)
etc.
