Hello,
Have you contacted your instructor? She should be able to help you with any specific questions you have, and if more than 1 student is having problems with the same content, we will re-evaluate that section of the course and more or better explanations.
Should you ever have questions about the content of the course, you may email your instructor, Jan Bradburn at bradburn@oltraining.com
Click on your instructor's name to email her from within your course (have popups turned on) also add her as a contact in your Messages Block.
