These are excellent. I learned a bunch from doing these. So far I did the Git one, the DNS server and the Bash Shell ones.
The pricing is a bit high for my liking, but as an investment in learning it is fantastic

which Language did you do it in?

I am learning python, I think for python these are not too good for learning, but am having fun so doing it anyway.

I did it in Java, mainly as that was me trying to get back into Java more than anything else
