Rote learning is a learning technique which avoids understanding of a subject and instead focuses on memorization. The major practice involved in rote learning is learning by repetition.

Examples include, phonics in reading, the periodic table in chemistry, multiplication tables in mathematics, anatomy in medicine, cases or statutes in law, basic formulas in any science, etc.
Memory... is the diary that we all carry about with us. - Oscar Wilde. A photographic memory can be a very useful thing. You can use it to memorize cue cards for speeches, grocery lists, and phone numbers. Some of the national champions of memorizing can memorize 32 decks of cards, how the decks themselves are in a pattern and how the cards are organized, in an hour. Maybe you don't want to do these things, you just want to have a better memory than 99% of the world.
