I like to think that because Coco's older, she had a higher aura cap and can funnel more if it into her weapons. Meaning, if she was a first year, the shots would've bounced off the Death Stalker and only slightly hurt the Nevermores.

Same with Yatsu and his ground pound. That wasn't strength; it was Aura, and a younger student wouldn't have been able to do anything near as impressive - no matter how big they are.
