<p>Last year I was enrolled in my school’s physics B AP class which I found awesome, and as a senior this year I am in physics C AP. My schedule this year has one free spot and I am done with all my required classes, would it be ok to take that physics B course again??</p>
<p>Don’t. Just don’t. I’d rather not hash through all the reasons you shouldn’t. Since physics C does not cover thermo and waves in depth, you should take the textbook for c and learn those parts by yourself. Be blessed you have a free period and expand your horizons a little bit</p>
<p>Don’t do it, you think it’ll be an easy A but you’ll end up getting tired of the redundancy, depending on what you want to be in the future take another class, perhaps AP Chem, or AP Bio, or CAAD or something related. You can also just enjoy your free block like bananafreak said.</p>
