Well, for a start, it's "quarter-finals" and "semi-finals", not "quartefinals" and "seminals".
The logic in your example is wrong. The two rounds could be used the other way round.
"You will receive ten points if you reach the semi-finals, or at least reach the quarter-finals."
Having said that, that doesn't make much more sense. Surely you get more points for reaching the semi-finals than you do for reaching the quarter-finals?
You will receive ten points if you at least reach the quarter-finals. You will receive more points if you make it further in the competition.
