Pre-calculus is such a tough class. My dad is the teacher, and I'm still getting a D. I just don't get it, and it's not really helping that my dad is tougher on me than everybody else, just because he doesn't want people to think that he's playing favorites. I do all my homework, but it barely counts for anything (just 10%). Tests are the big part of our grade, and I just can't pass it. My dad does help me at home when I ask, but it never seems to be enough. And the school won't let me drop the class... I'm stuck in pre-calc, and I need to pass it or I'll have to take it again in summer school. What can I do to pass the class? I've asked my dad this question, and he just said that I need to do well on tests, but I'm having such a hard time doing that. What can I do?
