Is it possible to take AP Chem and AP Biology at the same time?

I am currently a junior setting up my schedule for next year. I’m considering doing two AP’s - AP Chem and AP Biology. I’ve heard that this is a heavy workload, so, I’ve been wondering if it would make sense to do some summer courses so that I’d have more free time during the year.
I already have a free period for one semester. If I take Participation in Government and Economics over the summer then that’s another period off for me.
So this is what my schedule would look like:
1 English
2 PreCalc
3 AP Chem/AP Bio
4 AP Chem
5 AP Bio
6 Physical Education / Free
7 Lunch
8 African American History/ Free
9 Free

I’d have at least one - two free periods each day (each period is 45 minutes approximately). Is it manageable/doable? Tell me your thoughts let me know if it makes sense.

I thought this would help me to have less all nighters. If anything, ill drop one now and fill my schedule with something else.

As someone who has experience with both AP Biology and AP Chemistry (though not in the same year), taking two demanding AP lab sciences at once is a very poor choice, and is unnecessary as well. If you’ve already taken some kind of biology, chemistry, and physics, then you’ve fulfilled all that is expected of you from almost every single university you could apply to. If you want to have maximum competitiveness, then you could take one AP science (it really doesn’t matter which) or another science you haven’t taken, such as Anatomy and Physiology, senior year.

No No don’t do this. Make sure you fit in Physics between now and next year and take one of the AP sciences.
