Sandbox Environment for Practice/Training?

Hello, wonderful Gainsight Community! 

I was recently laid off as part of a company-wide restructuring initiative. With my loss of employment, I no longer have access to my company’s Gainsight instance, and lost a valuable resource that’s crucial to my upcoming level 3 admin certification exam. 

I was curious if Gainsight has any sort of training environment, similar to how Salesforce does for Trailhead trainings, that I could utilize to continue honing in and perfecting my Gainsight admin skillsets while I’m on the hunt for a new opportunity? 

I feel this is crucial to my career as a Gainsight administrator, to not only stay on top of updates/rollouts, but also continue to fine-tune my skillsets and be the best administrator I can be, wherever I end up next.

Thanks!
