Hey y'all! I was wondering if Mark K is helpful for passing the NCLEX. I also purchased UWorld and about to get Archer. The reason I'm asking about mark k is because in one of his lectures he mentions that mumps and rubella are airborne precautions but I have always been taught those are in droplet. Also, in all my books it says droplet too. I've heard he is really helpful but now a little weary.
