Hello All, I am enrolled in a third year probability course, and the course text book is Introduction to Probability Models by Sheldon Ross. I want to do good in this course, and this course is the hardest course in third year stats. Therefore, I am studying from Ross right now, but would appreciate if you could give me the names of other books that are on par with Ross and much more problem-intensive, since the theory is already being covered in Ross. However, I do not mind a theory intensive book as long as it is problem intensive as well, and on par with Introduction to Probability Models. Thanks.
