Having just been through this, and still currently going through this, I can say that, at least in CA, that taking classes to get a better GPA for Cs and above are looked upon negatively. I was even advised by a counselor that a W looks better than a C and if I knew I was going to get a C, I should've just taken the W.
I totally feel your rant. I've been an LVN for 6 years and just finished my AA with my prereqs included in 2018. Like you, my GPA fresh out of high school was low - 1.2 dragging my overall GPA to 2.4, I should be a 2.75+. Even with an academic renewal, it was still low, and really, it was just for filler classes that don't even amount do anything.
Currently, I'm working on a non-nursing bachelors via Ashford University. I'm hoping with this, I can look for a second bachelors in nursing or a masters in nursing for non-nurses. I'm also very interested in Concordia University in TX and OR as they do an accelerated BSN for LVNs.
