When all content for Google Certified Associate Cloud Engineer will be available? It suppose to be September but still not there.

Hello, Zafar!  I’ve been heads-down on creating and recording lots of new content.  I finished editing and uploading the first of that, last night–including a new GCE lab–and more is on the way as I continue to work through it all.  The course will continue to grow, but you can read through all the reports linked from this thread to see how you can use what’s already here to support your run at a certification.
