Hello, Alexandrea
Thank you for your post.
The first thing you'll see is the challenge assessment. The challenge assessment is optional. Read over the instructions in the resources section for instructions on how to complete the challenge. If you decide to complete the challenge exercises, and they are acceptable, you will not be required to complete the remaining lessons in the Computer Applications section. You will be given transfer credit for this section and can move on to your next set of materials.
If you do not complete the challenge exercises successfully, you will still need to do the lessons. If you decide to not do the challenge at all, just start with the first lesson in this section.
If you have any further questions, please let us know.
Best of luck with your studies.
