I need to know how to memorize efficiently. Best and longest answer get Brainiest.

The way I memorize stuff is by continuously reading and listening to it. Mainly how I learn German and how I learn song lyrics. When I hear it long enough, and read the lyrics/german long enough, I remember it by memory. I hear there are some good Memory Exercises you can do but I can't remember off the top of my head, so try looking up some Memory Exercises and see what you can find.
