My guess Boruto got some ready made scroll(and he signed it based on the complexity/color of the seal). Why on earth would the academy have such a scroll, and if they had such a scroll, why wasn't the animal recognized?

He had significant trouble summoning anything beyond a tadpole, but the actual summoning part he figured out in no time. even then he summoned Gamabunta (jonin/kage level summon) with no effort simply because he had so much chakra.

Summoning itself is not difficult. Naruto just sucked at ninjutsu.
