Shudder. Hack College suggests that you should erase something you've memorised in order to fix it in your head. I think I went pale at the thought. Write something down, commit it to memory and then hit delete. I swear I just hallucinated a popup dialogue saying “This operation cannot be undone”.
But if you're braver than me, there is more about this and 19 less scary ideas for people with bad memories on Hack College's 20 Memorization Techniques for College Students. Also a great photo.
