So ... #DataCamp ... The most recent course was the most understandable course I've ever taken from them. This is #rlang + #tidyverse + #dplyr + #ggplot2 ... the guy didn't assume I knew anything, so he explained everything from the beginning. Also, the exercises expected one to put in everything. Exercises began with:

library(dplyr)
library(ggplot2)

and so on, so it wasn't mystery functions that just appear in the environment.

And that convinces me that the issues I'm having with their courses are mostly sourced in their educational methodologies.

Now, I don't want to scare anyone off from trying DC. But at this stage of my life, their methods don't work so well with my brain.

On the other hand, the #Google + #Coursera Cybersecurity program and the #IBM + Coursera Backend Development program seem to do the opposite. Because of their target markets, they assume students don't have much relevant background and they give lots of effort covering the most basic things in great detail.

Which is good, but in some cases, it is hard to pay attention to things I've known for over twenty years.
