I had trouble connecting to the ec2 instance from rdp. It was not explained well. I lost too much time and had to restart

There were errors in the instructions, and I ran out of time troubleshooting. :-(

It was good, but after some issues with the RDP (connection briefly lost multiple times) and JDBC directory button sticking, and JDBC issues, I only reached just beyond the ML model evaluation. I am disappointed I couldn't make some predictions. I will re-read the end of the lab so I understand what I was going to do. I notice you are still showing Redshift structure images in the texts that are tiny and cannot be expanded. I see no benefit in these images.

Great lab, but it was like trying to beat the clock, it could use another 30 minutes so you don't feel as rushed.
