No. The ORSC course is a series of five modules and each module is a prerequisite for the next. Each must be taken in sequential order because the content follows on and builds.

The order of study to achieve ORSC​ certification is:

#1  Fundamentals or  ORS@Work
#2  Intelligence
#3  Geography
#4  Path
#5  Systems Integration

However, course modules may be taken at any time (and in any country or city) of your choosing.
