My suggestion, you need a workshop..if you cant do an in-person one, i highly recommend the online one at least! practice care plans, they are the make it or break it part of the PCS...you either make it and get into the room or break it and you walk away without ever laying eyes on your patient.
I spent 7wks preparing. I did my online workshop (also took the in-person one), care plans 2 per week at least, plus the free EC ones. memorized and wrote out mnemonics daily for a week, the next week, worked on care plans, menmonics, and started one lab, the next week did care plans, mnemonics, lab 1 and lab 2, the next week was care plans, labe 1, 2 & 3, and mnemonics...etc til i was doing it in my sleep. anything or any skill i didnt know i used Taylor's skills videos (can find them on ebay for cheap) and whenever i started making mistakes i took a break...one day i was so messed up doing labs i walked out of my house and went and caught a movie by myself and went shopping for white scrubs (so that i could be comfy and not in starchy crappy walmart ones, i wanted good soft ones! LOL) it was the best thing for me...the final week before testing i only looked at my stuff for an hour or so per day.
