Advice and feedback for these AP classes?

Hello everyone, I’ll be taking AP History, AP English Language, and AP Biology my junior year. I have passed every course that I have taken so far with an A or higher average but I’m worried that I won’t be able to do that this year because of my course load. In addition to these three AP classes, I’m also taking Trig honors, precalc accelerated, and Spanish II honors. I feel like I’ll be going home each day with at least 6 hours of homework. For those of you who have taken any of these classes, do you have any advice on how to succeed in them? Also, how many hours of homework did you have on average for any given class?
These were my averages from last year for history, english, and biology:
-US History I honors 100%, and no that was not an easy class, I just worked “very” hard. In fact, the teacher told me that I was the first student ever to pass one of her classes with a 100% average.
-English II honors 98%
-Biology Honors 97% (yeah for some reason, I was never really able to consistently get the high scores I needed to maintain an A+ average in here, I never scored below a 90 on a test but I was never able to score higher than a 95 more than twice in a row. My test average at the end of the year was a 93%, the 97% is just a result of homework and lab report inflation.) Either way, I really like science, and at the encouragement of my teacher on course selection day, I circled AP Biology.

100% depends on the teacher.

I agree w/the above. It depends on the teacher most of the time, but [url=<a href=“http://www.fcps.edu/westspringfieldhs/student_services/assets/academic_advising/ap_course_expectations.pdf%5Dhere%5B/url”>http://www.fcps.edu/westspringfieldhs/student_services/assets/academic_advising/ap_course_expectations.pdf]here[/url] is a chart I found online that can help give you some insight on what to expect.
