While I did learn reading, writing and math, my writing skills were subpar and this was never spotted or addressed. More importantly most of the writing skills taught were essay writing or letter writing. The former isn't particular relevant to the writing I do in day to day life and the latter was archaicly formal. The most valuable writing skills I got from school were actually science report writing (helped a lot with documentation and communication in a work setting) and even then I've learned far more from organisational roles in my hobbies and during my career than I ever did at School (or the formal education part of uni).
