Maybe you should go to the teacher and tell him/her that you need extra help. I bet they will give you extra credit work. If you become “friends” with the teacher they are more willing to help you out. I dont mean suck up, but act interested in the subject. And remember that its only what? 16 weeks? Thats not long, plus your almost half done by now, and its a lot of money for a class nowadays so just work super hard. Itll be over before you know it. Try and find a tutor to help you, most colleges now have free tutoring either online or in the school. Some even have you sign in so that you get credit in class for seeing a tutor for that subject. Either way, good luck. Im taking microeconomics now and its a lot easier than i had imagined , but i havent tried macro yet. Good luck!

just do good on the next stuff u will be fine 40% is better than nothing.
