Do you remember anything from the school curriculum?

Surprisingly, I remember almost everything: that is, if a student, for example, grade 10, comes up to me and asks to explain a topic in mathematics or biology, I will most likely be able to do this without even looking at the textbook.

But I had a very good school, where they taught to understand, not memorize. Plus, I myself constantly specially restore in my memory knowledge in basic school subjects - for example, at Khan Academy. Oddly enough, it helps in life and work.

1. London is the capital of Great Britain.
2. Chloroplasts contain chlorophyll.
