Took my exam recently & would like to say CS EXAM can get pretty stressful under time pressure. I would say everyone should work on time management for the encounter as well as PN. In all my PN's I needed a little more than 10 minute time , my typing speed wasnt that great but it wasnt too bad either, I felt usmle wants us to be great future typists
. Try to save some time in your encounters instead of waiting for the last announcement. Even one extra minute for PN is a lot of benefit.
Did the first aid cases mini cases + long cases, prepare them well & learn the D/D's & work up. I still have mixed feelings abt the test. Its not a very hard test but it does make you a little crazy under time pressure
so my advise dont take it very lightly & go with full prep for encounters,closures & PN writing. All the best !
