Totally sad that there is a scheduling conflict - based on your stated goal of MechE or MatSci engineering, you would be best served to dump the AP Bio and take the AP Physics C & AP Chem.
You are obviously one of the star students at your school - perhaps you could convince your school to add an extra class for you? No harm in asking IMHO - and they just might be able to do it.
Congrats on the patents pending BTW! My son’s GF has a couple of Med patents pending also - and he says she is the most brilliant person he knows.
