Listen up, ladies and gentlemen. Here are things to think about.
First, you need to know what you don't know. I suggest you attend lectures and tutorials, and if those are too boring, spend the time reading the material and making sense of it. Somewhere in all that, you will learn what it is about the material that is impervious to the razor-edged sharpness of your brain. Alternately, you might learn that you know it all. Good for you.
Second, you need to list the things you need help with. Don't come to me with, "I don't know anything, help me." I will proceed to spend time showing you what you do know. But that might not help you with what you don't know. And trust me, everyone knows some things. I can prove it to you.
Third, if you have not overcome the difficulties highlighted in the two previous paragraphs, and you come to me with only a day or two left, pray for miracles of cognitive blossoming. That might help. I can then help you blooming students in the confidence that not my will but the divine will shall be done.
Last, you really might be screwed, and it will certainly not be something I am to be faulted or blamed for. (Incidentally, you should know the difference between 'fault' and 'blame'. If not, search this blog till you find it.)
