Expectations

Have you ever thought something was good, just to find out it's not good enough?
That happened to me today. I wrote a math test and got a 75%. I though that was pretty good because a know that the average for the class was 64%. I came home and showed the test to mom, thinking she'd be pleased, but she had a fit. "Rythia, How DARE you get a mark like this?!? You KNOW better! You should have gotten 100% and nothing less" (End quote) I'm rather ticked right now. I hate it when she does that.

Anyways, i need some feedback on how to deal with this.

Cya.
