APs, homework, and studying

Hi everyone, I was just wondering what a rough estimate of the amount of homework and studying there would be for my prospective junior year schedule (keeping the things in parenthesis in mind):

Conceptual physics (This is academic since I don’t have a strong science interest)
AP Economics (Do not know much about, but am interested in; apparently teachers at my school suck for econ though)
APUSH (Have an A- in AP world history; have an interest)
Study hall
AP Calc AB (A in Precalc/overall strong in math)
AP Lang (A+ in honors English and a passion/interest for it)
Spanish 5 honors (A+ in Spanish)
AP music theory (Strong musical background, 10 years of violin)
