How can i get my grades back up to all A's?

I suggest that u improve on the grades that are falling way to low like AP european history,speech and debate, and watch out for chem. U gotta plan out what u really need 2 improve on. The cles u still hav A's in u jus gotta be more careful. The ones that r in the B range near C those are the ones you should work on. Since your school doesn't have extra cred I think its best to talk to your teacher about future work and tests. If u start early and try real hard ur A's will be coming rite back to u. Also ask if u can make up any work from the past that you've missed if not then just totally focus on whats ahead. Try doing everything before hand, but don't stress or panic cuz if u do ur going fall more then improve.
