First day blues

Today was my first day of class for this semester. I am officially an Accounting major. All the class I’m taking are about business literally right next door to each other. I’m taking 18 credits and I had four class today and tomorrow I’ll have two more. I am terrified of one of my classes: Principles of Marketing. Through out the semester we have one huge assignment, creating a marketing plan for a business of our choice. I have to work in a group through out the semester. I don’t know if I am going to be able to do that… I have no marketing background what’s so ever! And I hate working with in a group. I don’t even know that many people to feel comfortable enough to put a group of five people together. I don’t know if I am just afraid of a challenge or if I am reasonably concerned with my abilities to do well in that class. I’m going to have take the class eventually but I’m not sure if right now is the right time. I have a week to decide whether to drop the class or not.
