Xpectation vs Hope

What is Expectation and what is Hope?

many quotes which i had came through always said that “expectations gives you disappointment”

“Hope is the first step to success”
for eg: i will score 100 in maths exam?

is this hope or disappointment?

its based on the results it seems…

When the mark is 100,the its hope

when the mark is below 100 even its is 99,its disappointment
