Yeah that point might have been a bit exuberant. Nevertheless, after 3-4 years I think you have covered most grammar topics, maybe excluding passe simple and subjonctive. In English you'll continue to learn new concepts such as "contact clauses" etc
I'm only doing this because of the topic of conversation, but you probably meant to say that your point was a bit exaggerated instead of exuberant (which means something along the lines of energetically happy).
That's the only mistake I noticed reading through, so I have to congratulate you - I wouldn't've noticed you weren't a native speaker.
Using words that just don't perfectly fit is probably a good illustration of differences between a speaker of near-native proficiency and a native speaker. Choosing odd words here and there.
