I'm doing the math and unless your professor drops the lowest score, I don't know how an A is attainable in Biochem.
Also, I don't know how if there is a chance with Microbio as well. Especially with labs and lab papers kinda depend on who is giving the scores.
Your GPA is on the low side, you can't afford another C.
getting B for both is a good compromise, but you have to work hard to pull it off.
Or at least try your best to get an A in one of them and B in the other.
