Easiest RN to BSN?

[Pebanj]

I'm overwhelmed and stressed out, I work full-time, have kids (8-15, two with special needs), I'm divorced with a dead-beat ex-husband, and my work is requiring me to get my BSN. I do not plan on going back to school after the BSN (previously thought I wanted to, but have found I love what I do!). I just need something straight forward, not overwhelming, not terribly time consuming, that I can complete in 18 months or I need to start looking for a new job - I really like my job though!

I started at WGU and had to drop because I was so overwhelmed with the biochemistry class that I couldn't get past it. I passed statistics in just 2 weeks, though. The classes had so much content in so many formats to get through that I was full of anxiety and felt sick all the time.

I'm OK with paper writing, but would prefer not to have to take online proctored exams (my house is never quiet or calm enough), and other center-based proctored exams are OK occasionally (like end of course), but not frequently through the class.

Please tell me what schools might work for me!
