Hello. I will be attending a course on Group theory and the book that the professor suggests is Georgi's Lie Algebras in Particle Physics. As I liked Zee's book on General Relativity, I thought that it would be a blast to also use his Group theory textbook for the course. Problem is that I don't know if the level of Zee's book matches that of Georgi's(I wouldn't want to solve exercises from Zee that are at a lower level of that of the examination which will be at the same level as Georgi's book). Any help is appreciated!
