Hello, i am currently planning my schedule for senior year. Is it possible to survive AP Calc BC, Physics 1, and Chem all in the same year? Are they easy to keep AT LEAST a B average? I would also be taking APES< AP gov and econ. Would i survive? How hard would it be to keep a 4.0 WEIGHTED? How much time would i have to spend in studying and homework?
Thanks 
Is it possible? Yes, many students take AP Physics C, AP Chem, and AP Calc simultaneously, so AP Physics 1 would be a walk in the park.
Since we do not know you, it would be presumptuous to say if your GPA would suffer, or if you would survive. The workload is dependent upon the teacher, so ask current students how long they spend on homework. My experincece has been 45-60 minutes for Chem, Physics, and Calc, and 20-30 minutes for the others, buy YMMV.
My D is currently taking AP Chem, AP Physics 1/2, AP CAL BC, AP Eng Language, AP US History, Pre AP German 3 and orchestra. I don’t think it’s “easy” to keep a B average in any AP course they all take work! She has about 2 to 3 hours of homework a night but does some homework at school too. She has maintained A’s in all her classes.
Senior year she plans to take: Orchestra, AP Music Theory, AP German 4, Physics C, and AP English Lit (seminar) at high school and Am Gov, Economics, Speech, Cal III as dual enrollment at a CC and college Statistics on line.
So yes it’s doable if you are willing to put in the effort and keep on top of things, not a course load where you can let things slide.
You should provide more information before asking how well you would do. What is your current course-load? current GPA?
