How do I scope my final count variable properly?

Is it fair that tests count 70% of the final grade?

• I just moved away from city this school year, then I attend a school in a middle-class average income suburb. In city, the school was extremely easy. I did nothing and get all A's (well, the teachers actually don't give a lot of woks to do, so I usually finish ALL my homework within a hour). However, when I move to a suburb school, the teachers always give a lot of classwork and homework, which I always have to spend at least 5 hours a day to do all my homework, AND they only count the homework for 10% of your final grade. Most teachers gave 50%-70%(especially honor classes, even 80%-90% for the AP's) of the final grade section for tests (while city teachers only count tests as 30%-40% of your final grade, and only 50% for the toughest AP classes). Is it really fair for students? Well, I feel okay for everything the teachers taught in the class so far, and I still have straight A's right now. However, the problem is, if I mess up one SINGLE test in my high school life, it'll directly hurt my GPA. Basically, I have to know all the stuff teachers told me in the class in order to get a higher score on the test. I also wonder if it's the same for college? I heard that most colleges only look at what you have on the test, but not how hard you work. Thank you so much if you'd like to answer me!
