so i have august off. i'm travelling the first 2 weeks which im not cancelling. i have ck scheduled 16 days after i come back, on a weds. CS is scheduled 2 days later, on a friday. i start a rotation on monday. so the only way i can get more time between CK and CS is to move CK up a day or two and have less time to study for it, when everyone says it is the more important of the two. so the only thing i can do is move CK earlier by a few days, but then i'd have less time to study for it. and on top of that, no matter WHEN i take CS, i will not be flying in any earlier than the prior morning, so it's not like i would schedule my flight out two days in advance and pay for a hotel for 2 nights. so having more time between CK and CS is only for studying purposes; regardless of the timing of CK/CS i would be flying out ~24 hours before my exam at the absolute earliest and any scheduling/flight cancellation issues would be identical.
