I am pretty sure. You should ask a teacher because they will most likely help you get the correct answer so that your grades don't drop. I think just follow your brain and heart and the answer should come to you. If it is wrong, say to a teacher something along the lines of "Hey! I really thought I did a good job on this one. Could you maybe help me find the correct answer?" The teacher will most likely say yes they will help you and if not ask a parent, sibling, gaurdian or any trusted person that will help you!
