My memory was never a prodigious one, except when the subject/thing was really important and interesting for me, but lately it seems my memory's getting weaker, and I'm not talking about those moments when I stand up, get out of the room and forget the motive - no. I'm talking about school-related things, like studying for a test, because this is my newest problem: I forget about them. My mother would say that I am not truly interested in them, but that can't be true, because I've never forgotten that I was going to have a written test the next day(s), never. I'd put the book on my bed, put on some music and search the internet for a while and simply forget about the book.
Is there anything I can do to improve my memory at least a bit? I'm used to forgetting things, what I don't want is to get used to forget important things too...
