SDN Members don't see this ad. (About Ads) I have 1 week left to cram/study for the ASE (american society of echo) board exam. Other than the ACC echo SAP CD, can someone recommend other sources? I have read some of Feigenbaum textbook and Oh textbook, but I won't be able to read all of Feigenbaum before the exam. Besides that, I know that often questions on these types of exams can be about minutiae and not necessarily understanding the concepts. I feel like reading the textbook is helping me with the latter, but I'm not naive enough to think that will be enough to pass a standardized test that reportedly has a fairly high failure rate.
