Re: I test on Saturday: Now, I'm feeling a bit nervous.
You seem to be VERY ANXIOUS about taking this test. I would suggest that you start drinking heavily now. By the time Saturday rolls around, you will be sufficiently chilled to do just fine on your test.
On Second thought, it is ONLY a test. Nothing really lost, nothing really gained. You have already learned what you need to know for the test. You are simply being asked to demonstrate that with which you already know and can do.
Then again, as the old saying goes " a bottle in front of me, or a frontal lobotomy?"
Good Luck although I doubt you need luck!
