The quality of instruction in high schools varies tremendously you might have done very well at a very poor high school, and that would not be an indicator of your chance of success here. This is a 3 credit hour course, which translates to 9 to 12 hours a week of work. If you don t have enough time, you should not take this course. Having internet access at work does not count. I doubt if your employer is going to be willing for you to spend an hour or two of the company s time every day completing your class work.
Work is due every day of the week.
You can always turn work in early if you know that there will be a day when you will not be able to be online. No class to go to you ve got to find the time and do it without a structure. You will earn the same course credit that you would earn if you attended a lecture-based course. You should be able to pass exams that cover the same material that the lecture course exams cover. This is fair and reasonable.
