Yes and no.  Our courses are instructor lead and are broken down into weekly modules.  As long as you can complete the assignments by the deadline indicated in the course, your time online is up to you.  Some instructors may have specific times they'll be available via chatrooms.  These chats are optional and are meant as an opportunity for you to discuss assignments and receive additional instruction.

Generally, our classes are 5 weeks long with assignments, lectures, exercises, and more due each week.  Students should expect to spend 8 hours per week on course work.  The advantage of online training is students can take as little or as much time as they need to learn the week's material prior to the module deadline.

No. The instructors will lead the class of students through the material one week (module) at a time.  Each module becomes available upon completion of the previous module.  You'll only have access to the course information one module at a time.

In general, you'll receive credit for participation in discussions, as well as your grades on weekly tests, assignments, and exercises.  A score of 80% or better is required to pass the course.  

Our instructors will be available for you to contact via email throughout the course.  Simply email them describing the problem you're experiencing and they will help you.

You're responsible for managing your time so the course deadlines are met.  During the 5 week course, it's suggested you login daily to complete course work in smaller sections rather than waiting  and trying to do it all at once.  Your instructor will work with you throughout the course to keep you on track with course assignments.
