Failure to pass the exam resulting in additional $150

I find this a tad unfair given, most people taking this course are employed and are snatching time to study and pass the exam. However, little is known that when one fails, one needs to pay additional $150 to sit for a second attempt. Most prestigious known certification examination institutes offer the 2nd attempt for free. something to consider!
Overall good course content with supporting videos and options available for download (offline study).
