Parents Expectations

I'm currently in the 10th grade going into the 11th and I have very traditional Chinese parents. In fact, my subjects in school was also due to me wanting to please my parents, particularly, my dad. My mum is rather leniant and relaxed, yet at the same time, she's too relaxed so it feels as though she doesn't really care about me when I know she definately does. Going into the 11th grade, my dad wants me to start tutoring in both physics and chemistry in order to try for a high grade in both school and the HSC, but that combined with me already going to 2 maths tutorings and an english tutoring and also because of being in an accerlerated maths program, I feel like there's a crazy amount of pressure to perform in school assigments, the HSC, tutoring and at home and I can't really confront my parents because their English isn't good enough to hold a conversation and my Chinese isn't good enough to get my point across. I honestly don't know what to do anymore.
