Meanwhile, Ron was reading two years’

Meanwhile, Ron was reading two years’ worth of Charms notes with his fingers in his ears, his lips moving soundlessly; Seamus Finnigan was lying flat on his back on the floor, reciting the definition of a Substantive Charm while Dean checked it against The Standard Book of Spells, Grade 5; and Parvati and Lavender, who were practising basic Locomotion Charms, were making their pencil-cases race each other around the edge of the table.

Dinner was a subdued affair that night. Harry and Ron did not talk much, but ate with gusto, having studied hard all day. Hermione, on the other hand, kept putting down her knife and fork and diving under the table for her bag, from which she would seize a book to check some fact or figure. Ron was just telling her that she ought to eat a decent meal or she would not sleep that night, when her fork slid from her limp fingers and landed with a loud tinkle on her plate.

‘Oh, my goodness,’ she said faintly, staring into the Entrance Hall. ‘Is that them? Is that the examiners?’

Harry and Ron whipped around on their bench. Through the doors to the Great Hall they could see Umbridge standing with a small group of ancient-looking witches and wizards. Umbridge, Harry was pleased to see, looked rather nervous.

‘Shall we go and have a closer look?’ said Ron.

Harry and Hermione nodded and they hastened towards the double doors into the Entrance Hall, slowing down as they stepped over the threshold to walk sedately past the examiners. Harry thought Professor Marchbanks must be the tiny, stooped witch with a face so lined it looked as though it had been draped in cobwebs; Umbridge was speaking to her deferentially. Professor Marchbanks seemed to be a little deaf; she was answering Professor Umbridge very loudly considering they were only a foot apart.

‘Journey was fine, journey was fine, we've made it plenty of times before!’ she said impatiently. ‘Now, I haven't heard from Dumbledore lately!’ she added, peering around the Hall as though hopeful he might suddenly emerge from a broom cupboard. ‘No idea where he is, I suppose?’

‘None at all,’ said Umbridge, shooting a malevolent look at Harry, Ron and Hermione, who were now dawdling around the foot of the stairs as Ron pretended to do up his shoelace. ‘But I daresay the Ministry of Magic will track him down soon enough.’

‘I doubt it,’ shouted tiny Professor Marchbanks, ‘not it Dumbledore doesn't want to be found! I should know ... examined him personally in Transfiguration and Charms when he did NEWTs ... did things with a wand I'd never seen before.’

‘Yes ... well ...’ said Professor Umbridge as Harry, Ron and Hermione dragged their feet up the marble staircase as slowly as they dared, ‘let me show you to the staff room. I daresay you'd like a cup of tea after your journey.’

It was an uncomfortable sort of an evening. Everyone was trying to do some last-minute revising but nobody seemed to be getting very far. Harry went to bed early but then lay awake for what felt like hours. He remembered his careers consultation and McGonagall's furious declaration that she would help him become an Auror if it was the last thing she did. He wished he had expressed a more achievable ambition now that exam time was here. He knew he was not the only one lying awake, but none of the others in the dormitory spoke and finally, one by one, they fell asleep.

None of the fifth-years talked very much at breakfast next day, either: Parvati was practising incantations under her breath while the salt cellar in front of her twitched; Hermione was rereading Achievements in Charming so fast that her eyes appeared blurred; and Neville kept dropping his knife and fork and knocking over the marmalade.

Once breakfast was over, the fifth- and seventh-years milled around in the Entrance Hall while the other students went off to lessons; then, at half past nine, they were called forwards class by class to re-enter the Great Hall, which had been rearranged exactly as Harry had seen it in the Pensieve when his father, Sirius and Snape had been taking their OWLs; the four house tables had been removed and replaced instead with many tables for one, all facing the staff-table end of the Hall where Professor McGonagall stood facing them. When they were all seated and quiet, she said, ‘You may begin,’ and turned over an enormous hour-glass on the desk beside her, on which there were also spare quills, ink bottles and rolls of parchment.

Harry turned over his paper, his heart thumping hard—three rows to his right and four seats ahead Hermione was already scribbling—and lowered his eyes to the first question: a) Give the incantation and b) describe the wand movement required to make objects fly.
