Ethics - CFAI or Schweser allocated, important, breaker

badonkus

I saved ethics til the end and I haven't spent any time there yet (prob not smart in hindsight but it made sense to me several months ago). Is CFA text a must for ethics or will Schweser suffice? I have at least a couple days out of the next 11 allocated to ethics, so time is an issue but not a deal breaker... I know how important it is. So CFAI or Schweser?

Thanks in advance...
