Perhaps worth reading through the rest of the comment too? I had other teachers where it was easy to pass and get good grades (As even), but I did not call them out as good.

Before jumping to conclusions, maybe ask for context too? In particular, this was a high school for gifted math kids, and what I learned through regular classes let me pass math uni entrance exam in the top 10 (out of ~500 students) with no extra prep and even easily pass a couple of semesters of uni math with almost no prep (I took exams for two semesters after the first semester). My (lack of) working habits did catch up to me after that.

Also, for 4 years in two uni degrees, I did not get such a good teacher ever again, and there were a few who were easy to get great grades with.

Perhaps you can give some benefit of the doubt, though?
