As a student studying in South Korea, what changes you think must be made in the education system to make it better?

Explanation:

studying hard is the only thing that could make the educational system better

I think the student when he studying first time then first he want to speak Korean and study hard for that but if he try then only he can be better

Explanation:

and he or she should have interest to study if he or she have interest then only their education will be better

and if he / she didn't have interest on study then we can't do anything

i think the answer is a and b

i wish you luck

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
