Well, I'll probably use this thread to get some advice.

So during my graduate coursework (CS), there were a couple of courses which required the class to review and present various papers. When my turn would come, I would prepare really well, make good notes and I would say reasonably fine slides. But then, when I would present, I would just lose the context when going over the slides. Eventually I started keeping more text on the slides and would end up reading off it, which is awful for the listeners.

Is this stage fright? Or perhaps poor memory? Or something else may be?
