I personally think they are being too harsh. However, do the best you can--and if they fuss, then try to take it in stride. They have some "kooky" issue. My parents expected a great deal from my sister and me. Sometimes parents try to live through their children or maybe they are afraid you will do poorly. I'm sorry you're having to go through these unrealistic expectations. I personally know how upsetting they can be. Remember, though, that when you do the best you can, you are ultimately doing it for you and your future. Good grades will get you into a better college, etc.
