I'm a graduate of CSUDH but also faculty. I'm not sure when NurseGina17 attended, but there is no math test. There is a graduation writing requirement, which all of the CSU schools have, but it can be done via essay with a proctor. Yes there is a weekend health assessment lab.
The clinical courses with preceptors have been reduced to 2 - leadership/management and community health. Preceptors for the leadership are quite easy to find as typically there is a qualified BSN prepared manager in your workplace that could serve as your preceptor. The Community Health involves either a public health nurse or school nurse and that can be more difficult to arrange.
I encourage you to look at the curriculum to see what looks most interesting and to consider how courses are delivered and if that suits you.
