Harry bit his lip absently as he began to write. A negative concentration would cause an alteration on the potion’s effects, most often the opposite. But there was something different about the effect of having a negative concentration in an invisibility potion. Obviously it didn’t to the reverse because that would just make you visible again…it was something about disappearing and…not wearing off! That was it!

The effects of a negative concentration for any of the ingredients of an invisibility potion causes the user to lose whatever the potion is applied to instead of merely turning it invisible.

The afternoon exam for Monday had Harry and Ron heading for Divination while Draco and Hermione took their Arithmancy exam.

Draco nearly groaned when he saw the prediction he had to make. This was another ‘locate the derivative of theta’ problem. And that would dictate his life span. Of course it would come out to have conditions, so it wouldn’t be a worthwhile calculation anyway. And as he scanned the parchment, yes, that was the second question: Is this an exact calculation? Why or why not?

Harry sat staring at Ron’s palm in silence as Professor Trelawney watched them. Ron had already written his prediction for Harry, which sat on the table, face down, next to them. Harry frowned slightly and began to write.

Ron’s life-line is very short. He will die exactly four weeks from now at my wedding. From the line over his thumb, I can see that he will get very drunk and endanger the life of one with a very strong Inner Eye (shown by the intersection of lines across the fingertips) and kill himself in grief, as shown by the perpendicular line running towards his palm from his life-line.

Harry sat back satisfied, having completely disregarded anything factual about palm reading he might have known. And if he was lucky, Professor Trelawney would read it and think the one with the very strong Inner Eye was hers. That way she wouldn’t come to the wedding.

The Care of Magical Creatures exam took place in a classroom on the second floor. Harry took a seat behind Draco and turned over the parchment on the desk which activated the no-cheating bubble Hagrid’s untidy scrawl covered the first few lines of the paper.

Describe any magical creature you wish in a completely developed essay.

Harry blinked and began thinking of which magical creature he should write about. His eyes fell on the outline of Draco in front of him and he smiled as he began to write.

Veriae, or Atra Veritas, are perhaps one of the most misunderstood magical creatures…

McGonagall’s Transfiguration exam was set up much like Snape’s Potions exam. The first half was a writing section and the second half was a practical. Draco finished writing the essay (What is the difference between transfiguring inanimate objects to animate ones and transfiguring animate objects to inanimate ones?) and turned the parchment over. It disappeared and a small box with a note on top appeared in its place. A small garden snake was in the box, stated the note, and the practical half of the exam was to turn the snake into a goblet. Draco flicked open the latch on the box and let the snake crawl out on his desk. Feeling for the magical currents in the room, he latched onto one hovering over the window, an earthen current. He gently guided it into the snake’s aura, blending the two and then began to mold the earth current into that of something with gold and gems.

Harry was having a more difficult time of the practical than Draco.

“But I don’t want to become a goblet!” his snake hissed pitifully. “They’re no fun! If I have to become something, make me something that goes places and sees things!”

Harry frowned. The snake continued to break his concentration with its whining about how it did not want to become a goblet. And he was sure he couldn’t ask McGonagall if he could transform it into something else simply because the snake liked it better!

Frowning he closed his eyes and tried to block out the snake’s speech as he thought of all the aspects of a water goblet.

Harry napped most of Wednesday in preparation for his Astronomy exam. Draco had taken it the night before, so the two of them just stayed in bed until lunch when Draco dragged them out to get something to eat. Then Draco had to take his Ancient Runes exam as Harry attempted to get more sleep. But sleep was not forthcoming, and Harry found himself envisioning many disastrous meetings between the Dursleys and Draco. The Astronomy exam left Harry exhausted for his History of Magic exam as he tried to write down everything he remembered about the Wizard-Troll wars of 1000 B.C.E . Finishing the exam he was very happy to simply fall asleep on his desk. Ron woke him shortly after the exam was finished and they headed for Herbology.
