How to memorize the dictionary?

This guy memorizes the dictionary and explains how at 5:28 but does he use the major system or the PAO system I am confused. Please help

Interesting video! Thanks for sharing. As for the number system he may have used, I don’t know either. He says 297 is a book for him, and it’s a book because it has a ‘special meaning’ for him. So he may or may not be using the Major or Dominic system. I think for a 1000-object system for 000-999 you could even just use arbitrary objects (though it would be slower to learn) and it would still be just as effective if practiced properly.

I do like his method of using numbers as pegs and then using an association of those pegs (such as book for 297) to link him to a location (a bookstore he’s familiar with).

3 digit Major system with 10 categories would make sense based on that example as 297 could be _bk, no?
