One Busy Weekend

I have been going crazy trying to keep up with all the homework and assignments that I have. I am currently taking Chemistry 105, American Heritage and Civil Engineering 203. Between those three classes I have way more work then I could possibly due. Honestly Chem 105 should be 4 hour class for students who know Chem already, a 5 hour class for students who have heard of Chemistry stuff and a 6 hour class for students like me who have done absolutely nothing in Chemistry ever. American Heritage is a joke, based on hours spent reading each week it should be a good 4 hour class not a 3 hour class. So this semester I am taking 15 credit hours but really I am taking 18 credit hours and working part time. I am going absolutely nuts trying to play catch up to all the assignments that I cannot due. I am temped to drop AH and take a W but I don't know what the consequences of that action will be. To make matters worse, I have a pending Internship at CAT during the winter semester and It will be forfeit if my GPA drops to far. Luckily I have an excellent councilor and I set up a meeting with her tomorrow. Boy I hope I can drop AH or I think all my grades will suffer and I will have a nervous break down before the semester is over.
