Recently I’m wondering if it’s worth investing in mnemonic instead of annotating and reviewing. What do you think about it? Is it worth the effort or is the result the same as a good note and review to learn something?
I think that mnemonics aren’t a replacement for regular studying – they are more like extra tools that you can add to your studying toolkit.
You can download a free ebook from the how to learn memory techniques page. It provides a quick overview.
I’m not sure I’m understanding the question, exactly, but my initial feeling is that memory techniques enable you to recall the information in the text—for a test or, if you desire, for the rest of your life. Annotations/notes don’t do that at all; they provide additional information, make connections with other data/sections, and include commentary and asides. To my mind, they don’t seem comparable at all.
But, again, maybe I’m misunderstanding your question or what you’re hoping to achieve.
