The course should provide an acceptable level of learning and training. The credits for the course should be transferable or equivalent to a traditional classroom course. Beware of online courses that advertise a high price tag with little or no work. You don't want to shortchange yourself or your education. Before you actually start that online class it will be in your best interest to have access to a computer and printer that has internet and e-mail capabilities, preferably one that is in the comfort of your own home.
Most online courses require a great deal of actual time spent working on the computer.
It would be unfair to your employer and coworkers if you were to try to use the computer you have at work. Besides, you don't need the added discomfort of having to worry about your boss catching you doing your homework on company time. An online course is stressful enough without adding more stress to the situation. You could try using a computer that is available through some university computer labs, by buying computer time at various computer cafes that have recently become popular, or by going to your local library. Keep in mind though that online classes demand a lot of time.
