Hi All,
I'm currently studying and some time ago I read that before you start studying it's a good idea to use Personal Genius to get into the flow state for better learning. Also after studying use Memory Supercharger in order to better retain the material learned.
My Q is, firstly, if I'm studying all day long (and have breaks in between of course) will I only need to use Memory Supercharger ONCE at the end of the day in order to retain everything I've learned that day, or do I need to use it after each (break)SESSION during the day ie multiple listenings?
Same with Personal Genius. Can I use it just once at the beginning of the day or do I have to use again between sessions, or even when the subject matter I'm studying changes?
Any help will be appreciated!
