working the weekend before taking nclex?

i’m taking the nclex on monday and I am scheduled to work this weekend, 7a-7p. there may or may not be downtime for me to do last minute review when i’m at work. my test is at 1pm. i’m strongly considering calling out saturday to do some last minute review because i’ve read not to study the day before. would anyone recommend working both days over taking a day to study?
