The other night I was stressing about not stressing. The panic is still there, but it has just become normal.
I still have four more exams to do, so there's still plenty of cramming to be done. This weekend I'll try to get plenty of rest, plenty of sleep.
Still to come are the second maths paper, then a few days' break next week, then chemistry, physics and art in the final week.
I'm very interested in science and the environment, and I really would like to do environmental engineering eventually. I want to get into working in the area of renewable energy.
That's all ahead of me. Now, I'm just delighted the exams are here - no more waiting and worrying.
There have no been no major disasters yet, even if there has been a couple of unsavoury moments.
The second Irish paper was hard enough. The questions that came up weren't exactly as we had expected.
For example, on Maidhc Dain∅n, we were expecting questions on his time in England and America, or on funny incidents from his story.
Instead, we had to answer either about his parents and his brother, or about his personality traits.
The poetry was fair enough. But again, the main question on Cath ChΘim an Fhia was unexpected. I had to sit back and think a bit before I could answer it.
I suppose in general the paper made you think a bit - you couldn't just rattle off stuff you'd memorised.
Maybe that's a good thing - but only in hindsight.
The amount of attention I'm getting for doing this diary is unbelievable.
I keep hearing "oh, so-and-so was asking about you". My mum came back from tennis the other day and she said: "I'm freezing - I was stood outside for 20 minutes talking about you."
I'm sure it will all hit me after the exams are done.
I don't mind the attention - in fact I'm loving it while it's lasting. In school no one's really taking any heed.
They all know I write for the school magazine, so it's not entirely unexpected.
Still, I get a fair amount of slagging from my friends: I have a habit of saying stupid things and putting my foot in it the odd time, so now when I do that my friends just say: "And she writes for The Irish Times."
Even though it's great to be getting through it, I'm so tired. My whole body is wrecked from sitting in the same position for so long. I feel like an old woman, I'm that stiff.
And I have to remember that I'm not even halfway there yet - I have to keep my focus and concentration.
The other night at home, my mother and sister were telling me a joke, and it took about 20 minutes for me to get it. It wasn't funny by then. They just told me: "Go to bed."
I think my database is completely full.
