When I was in school, I used to memorize all topics of a subject except mathematics.
Then in exams, write what I memorized.
I had no concept of learning till I reached college.
In college, the subjects were new.
One of which was mechanical.
I really liked it, as there was practicality in each topic. Plus there were a lot of diagrams. Which helped in understanding in detail.
If I could see the diagram, I could write about it and pour all the knowledge.
Memorization is not wrong.
It’s just, you need it for getting your facts straight.
Conceptual knowledge doesn’t require memorization.
