Am I cooked?

I just bought new skis and I've been told they're basically race skis. I'm a little past intermediate, weigh 145, and it's about 158cm to my eyes. The problem is that the skis I got are 168cm, and 110 flex, the boots fit perfectly but are these skis gonna be too big for me? I don't even know what it's gonna change.

Does anyone know my chances of making it out alive this season?
