I had Completed the Ignition V8.1 Tutorial Videos.
How to earn the Core & Gold Certification free of Cost?
Since i'm financially unstable i wanted this ignition certification very badly because it will atleast help to step on to the next level of my career.
You can't get it for free. I think if you were an a registered integrator you use to be able to.
I'd try to get an employer to front for it.
For free you can make couple demo projects that will show your qualification in Ignition. I don't see how certifications themselves will help your career.
