Agree 100% with gutonc on ASCO SEP4, lots of errors and duplicates. hemeoncqbank.com has lots of good questions but didn't have enough time to go through it all.
Regarding the real thing, i felt it wasn't as well written as it should have been. Even ASCO questions are much better. Some of the questions were too simple (e.g. one lines, either you knew it or you did not), few were outdated, and other were made tough using tiniest of the details rather than medical reasoning. Less focus on core oncology, more focus on supportive care and basic sciences and stuff that an internist should be tested on rather than an oncologist. Not sure how I did, hopefully I passed....can't stand to take it again. I would love to hear how others felt about it......
