(Sorry huge post!)
Alice listened carefully to her instructions. She was expecting some kind of duel perhaps, a way to prove her newly learned and practice skills of defensive magic. With a creative imagination such as hers, she thought of dementors, boggarts even. But scarecrows where definitely not on her list of possibilities. Well, after defeating Andrei in their dueling practice, she should have a good chance of getting herself alive from this. Although something told her it would be much more demanding than facing a 6th year Slytherin.
“Right” she said nodding her head. She wasn’t quite sure yet what kind of logic she could use in fighting scarecrows, but hopefully that will come when she’s on her feet. As Whight stepped away, a slight panicky expression appeared on Alice’s face. She quickly whipped it away from her face with a deep breath, hoping he didn’t notice. So she was left all alone now with no help whatsoever. Perhaps it was supposed to mimic real life situations, where in fact she would be dependent mostly on herself. So in that view, Alice was glad she could practice this before actually going out in the field. Although practice or not, it still scared her senselessly.
The moment he said 'being' two of the scarecrows came rushing directly at her. Alice already had her wand out and shouted "Expelliarmus!". But her spell missed and only wounded the arms a bit. She could tell they were pretty strong and it was going to take a lot more to take them down. Hiding behind a large boulder, she couldn't even take a minute of breath as another scarecrow came from her behind. "Immobulus!" she said pointing her wand quickly at the flying scarecrow at her and it fell down on the ground paralyzed. With a few simple confringo spells the remains blew up in flames. One down, three more to go.
Her little victory only angered the others even more as all three came attacking her at the same time. She defended herself but still earned a few large scratches on the way. Finally getting an idea, she stood in front of the largest boulder she could find and called the their's attention. Two of them came rushing towards her and Alice waited for the last moment to use Conjunctivitis on them to damage their eye sight permanently. The two scarecrows were caught of guard and as Alice moved away, they crashed into the rock breaking their legs. She then used Expelliarmus to finish them off quickly and much more easier than they couldn't move. Still one to go.
The last one was really causing her problems. She couldn't see it and it would attack hidden behind the trees at the worst moment. It obviously had a much better strategy than Alice. In the last moment, she remembered to use Reducio to shrink the threes so there was no where else to hide. Now it was a much easier target than before. "Incarcerous" she said as her spell made the it get tied up by ropes and fall down to the ground. It was still moving and tried to untie the ropes. She levitated the scarecrow to the pound and let it quickly sink deeper into the water, as it was the quickest way she could think of to get rid of it without risking breaking the ropes with her own spell.
Finally she was done. And she was more than exhausted, as it took a bit longer than she expected. But at least she had handled it well in her own mind.
