Replying to First College Semester

Graduated high school 2 years ago and haven't gone to college yet. I'm starting in Fall this year at a community college.
Signed up for an 8 week online English class. Its English 1 (This introductory course in rhetoric emphasizes clear, effective written communication and preparation of the research paper.) at this school.

I'm wondering if 8 weeks is going to be to difficult since its normally a 17 week course, and being that I haven't been to school in two years. Anyone have any experience in this?

Checked Rate My Professor and the teacher is supposed to be very good. I've also heard online classes can be more difficult, but I have nothing to go off of since its my first semester.

Thanks for the advice.
