I've just finished an elementary analysis course using Spivak's Calculus. I did get an A in the course but only because the professor was often very generous with the grading. The course I am in currently is using Folland's Advanced Calculus text. At the same time I have also been studying from Rudin's Real and Complex Analysis which has been moving along really slowly. I find it exceedingly difficult but I still do plan to forge on ahead with it. I asked my professor about another book for more practice and he pointed me to Lar Ahlfors Complex Analysis text. Can anyone comment on Ahlfor's text and compare Rudin and Ahlfors? I am doing this all on my own. I will occasionally ask questions here on physics forums but obviously if the text is too hard it won't help me any as I am already struggling a lot with Rudin.
