LPN Online Competency Exams Pre-Hire

I need to take a few LPN Online Competency
Exams before a certain agency will hire me.
(haven't worked in a few years)

I reveiwed for a pharmacology test-30 questions/30 minutes.

I need to also need a (online)skills check list and
competency test which are also 30 minutes each.


Has anyone had a similar experience?
What areas/subjects should I be reviewing?
What is covered in an online skills check list
which isn't a demonstration type test?


The testing is through a national(private) online
testing site.
