CHONY NLN Pharm exam

HI everyone! I just got hired at Childrens Hospital of New York - Columbia medical center and I have my NLN dosage test on Wed. I know in previous years they would give a list of meds to study but they no longer do that. Can anyone give me any pointers as to how to study for this test. I have no problems with dosage calculations but i feel very stressed because they are giving me no guidance as to which meds to focus on. If anyone has taken this test or has any insight please let me know. thanks a lot!
