Is Daron Acemoglu's Introduction to modern economic growth a good book for someone with introductory knowledge of economics and looking to study graduate level macroeconomics?

If not what other book is a level below and is better suited for someone who wants to read a macroeconomics textbook?

Frankly, it isn't unless you have a very strong background in multivariate calculus and real analysis. Its highly proof-based presentation is very much for the graduate student. 

Normal undergraduate intermediate economics is taught with books like Williamson, Macroeconomics (5th ed, 2014) (I used this book, though the main text was an internal preprint of Villaverde and Kruger's undergraduate equilibrium macroeconomics text). Williamson, eg, offers a much simplified version of similar concepts.
