I am 42 also. While your GPA is low, you can write an addendum explaining your circumstances. From my understanding, they don't take account grade inflation but your work history would be a big factor in your favor. Also your age would make an incoming class more diverse. To get accepted you would likely need a high LSAT score to offset the GPA. Hopefully you can point to improvements in grades over time. I too have a low undergrad GPA but I also have a high GPA from grad school which unfortunately the LSAC gpa's calculator doesn't use. I will need to write an addendum showing improvements and a high lsat score. I am not familiar with the schools you listed but apply to a range of schools and don't be afraid to get input from the admissions dept. of the schools you want to go to.

I did a full Kaplan course about 20 years ago and thought it was trash. I think i could have had the same minscule improvements just by taking practice tests. Hopefully, its improved since then. Anyway, I did a month of live classes but found i was struggling sometimes and just decided to do the while v2 core curriculum course. I like it so far and think its way better than the Kaplan course i had but there are a few sections that are not explained too well. I think my main issue is timing because I'm not finishing tests but getting 170+ in blind review. I just hope speed comes with more practice. Just make sure you save the recent P.T.s for just before you take the real test. Another thing is the drill feature, apparently its really useful but they don't really explain howbto utilize it. RC will take the longest to improve so you may want to do RC live classes. I liked them especially the one with Josh aldy.
