what academic subject do you find most difficult and why? 怎么回答？

i find the most difficult subject is science.
because science needs logic,math,and anamnesis of acute.
we must understand it and then bring to bear it.

I think the most difficult academic subject is science because, there is a lot of chemical symbols to memorize.
Also, I also think that socials is pretty hard too, mainly because i don't really like socials.
