Ah, soonereng, I predict good grades in your future. Seriously, I don't want to live or die by an "A" or a "B", either, but I think it takes some practice to know when you're obssessing. If someone could have taught me how to study for less than "A" with an absolute guarantee that I'd pass, I would have given it some serious consideration. What happened, though, was that I would do the best that I could to master the material - and if I got an "A", dandy. One problem you will have is that you can no longer predict an exam once you've taken the first exam in a course - each exam (in Biochem, at least) will have 5-7 instructors with their own question styles - so you will never know quite what to expect. I was much more worried about not passing. Perhaps that's why my mod nick-named me "Chicken Little." I will admit - I am insufferable from about a week before exams until exams are over - best just to avoid me.
New topic: zoology! I was fascinated last night. I let Jesse, my German Shepherd, out last night - and all I saw was one big streak of fur. Turns out, by the time I got some lights on in the back yard, that there was a possum that she saw and I didn't. But, it looked quite dead to me - and I thought, "great - it fell out of the tree and now I have to get it into a plastic bag with a shovel." Not so! Jess quickly bored with the "dead" possum, but she wouldn't come in with such an interesting carcass in the back yard. Finally, it woke up and walked a few feet - Jess came flying after it and it promptly passed-out. I finally got Jess dragged inside - and, about an hour later, the possum was gone.
I did some reading on the internet - "playing possum" is a real phenomenon! Turns out the response is involuntary - the poor little suckers pass out when severely frightened - and their breathing is so shallow that they do indeed look quite dead - which bores the attacking German Shepherd. Remarkably effective defense mechanism.
I'm glad I didn't bag the little sucker up and put him in the garbage - the article on the web that I read said that being "assumed dead" is almost as lethal as automobile accidents to possums.
Fascinating. Here in Oklahoma City with my two 60-year-old oak trees, I have a little nature preserve in my backyard - I've actually learned a lot.
