Anxiety Roller Coaster

My anxiety is a roller coaster. I'm about to take final exam and I'm torn.
What to do, what to do?
You see, I have a good enough grade in this class that I don't really need to take the final to pass. However, this is the first semester in my college career that I have the possibility of having a "four-point" semester (all "A's").
So, I've been bouncing back and forth between "I'm going to study real hard and do real good on this exam so that I can get an "A"" and "I don't need an "A" in this class, I just need to pass".
See my conundrum?
This morning I've been buried in powerpoints and notes, and yet now I find myself typing up a blog post. It's been real hard to focus.
So what do I do?
Well, at this point I've told myself that "If you don't know it by now, you're not going to be able to learn it in the next twenty minutes." I've prayed for peace and the ability to focus once the exam starts. The rest just depends on time. The old saying is "Que Sera Sera" (Whatever will be will be). I'm going to do just fine, whatever the outcome.
I'm excited about the end of this semester (which is also the end of this test). Once this semester is over, I can focus on packing. Hawaii here I come!!!
