Cosmological Inflation and Large-Scale Structure
I would say that anyone using this book would need a sound grasp of most undergraduate level mathematical physics. Its a wide ranging subject, firstly because it starts from cosmology, but then adds on the complication of interacting matter (rather than 'dust'). Secondly, it looks at both models of the behaviour of the early universe, and observations of the universe today.
Chapter 12 gives a non-mathematical, (but still technical) summary of the subject and chapter 13 comprises a couple of pages looking at future possibilities. The last two chapters contain material which is more advanced than the rest of the book.
