Online classes require a certain degree of familiarity with technology. This does not mean a student must be a computer whiz. However, they should have a basic understanding of opening and creating documents and basic Internet and email skills. Most colleges have an orientation that lets you familiarize yourself with the learning management system that will be used, so it is beneficial for a potential online student to look through it to understand what they will be doing in class. They may also have a learning styles quiz to see what your study habits are, and if your habits would be a good match for online classes.
Not all online classes are designed the same. Some may have strict deadlines, while others may give you more flexibility when turning in your work. If that is the case, it is always a good idea to create deadlines for yourself so you do not fall behind and have to catch up at the end of the semester. Create a study schedule that gives you enough time to do all the required activities for a particular unit, as well as help you develop a routine for your work. Online classes require self-discipline, which means you need to be motivated to stick the schedule you have created. This includes planning for any "emergencies" that might occur, such as your Internet access going out or other computer malfunctions.
A common misconception is that online classes are solitary, but that is not the case. Online classes, just like traditional brick and mortar classes, have an instructor who is willing to assist you with problems and answer questions. Express concerns through email or other communication tools. When communicating, always make sure you are polite and use proper language. Once you have sent the email, you cannot get it back, so read through it to make sure you have expressed yourself well.
Other students are enrolled in your online class as well, and are probably dealing with the same struggles that you are. Try to get to know a few of them through the online discussion boards, or simply email some students with questions you may have. Express yourself and your questions politely and stay on subject. Other online students can be useful resources.
