This is a great question and has been followed by some good advice. Please consider your learning style when taking classes online or IRL. We all learn differently and we need understand how we can learn best to get the most out of the class. Do you like to see things written down? Do you learn by listening? Do you learn by putting things together? Classes IRL and online are similar in which they both require reading, writing papers, group work and so on. It takes a lot discipline to learn online. The one big difference is the in class time which will be mostly lecture. Make sure to fine tune your note taking and study skills as some of the things being said may not be written down in any of the books or resources.
Find your learning strengths and work with them to make sure you get the best experience in your college classes. Good luck!
