The chemical PE course now comes in only one "flavor". I have selected the option previously called the Premium Course as the only option for the reasons below.
The selected version includes the student/instructor Forum. I believe this forum will make it much easier for me to communicate with all students regarding possible errors and course updates. With the previous Basic Course, I was going to have to use email which is more difficult.
The VIP Private Course involved a couple of web services that greatly increased my cost. Eliminating this option also eliminated a lot of my time devoted to session scheduling and consultation, and web software maintenance.
Comparison with other courses
My course is currently priced at $475. This is ~$50 below the lowest price of the popular courses available. That course
does not have computer-based and timed quizzes and practice exams (none of the other courses have this feature). A student forum is also not available in that course. The course is not computer-based...notebooks are mailed to the clients. Communication with instructors is by email or phone.
The next higher priced course available costs $990. Written materials cost an additional $125. That course includes a student forum as in my course. One disadvantage of this course is the 60 hr. of video you have to watch. Communication with instructors is by submitting questions in writing on the course website.
The highest priced course costs $1616-$1916 depending upon the amount of time you can access the course. This course has 50 hr. of video. It appears there is no communication with the instructors in this course. A more expensive version of this course includes 10 office hours.
Free upgrade to Basic Course
I have upgraded previous purchases of the Basic Course to the new course at no extra charge. The early bird gets the worm!
