I'm in a bit of a weird situation. In the following remark (in Kunen 2011):
It says that 'rudimentary knowledge' of model theory and recursion theory is assumed. One option I have is to read Kunen's Foundation of Mathematics to get the necessary prerequisites. I have no idea of what 'rudimentary' means, so assuming that I read all the model theory and recursion theory material in the text, this would entail reading 160 pages worth of material. I believe that, on top of my schoolwork, this would take at least 3.5 months to read.
However, at the same time, I am taking a mathematical logic course this semester which I believe more or less covers all of this material - which would defeat the purpose of my self study.
Therefore, I would like to know the FASTEST way to jump into the material in Kunen's 2011 text, preferably a recommended reading under 80 pages.
(for reference, here is the part of Kunen's Foundations of Mathematics table of contents covering model theory and recursion theory)
