Just to let you know, the past tense of teach is taught; so you would say "I wasn't taught this at school". Other than that, your English is great (better than some of my fellow English people lol). Well done.
You are right, and thanks. Typing on mobile with alternative keyboard without spelling correction is a challenge. I was fortunate enough to be on a part Dutch/English primary school. That helped a lot with getting a lot of assumptions corrected. For instance as a kid I assumed the English word for "monkey" is "ape", because the Dutch word is "aap".
