I have been away from GIS and Esri for awhile. I was taking care of my sick parent. I am presently working outside of GIS field and want to get back into it. What are the best FREE Esri training courses to take to help me relearn ArcMAP 10.8.1 and ArcGIS Pro 2.6? I cannot afford Instructor lead courses on my very limited income. I will also need to learn Python and how that works with Esri so what Esri Python courses would be beneficial? I know UDEMY is available and would also utilize that when I can find extra cash. I noticed there were hundreds of courses at Esri so I paid for the 1 year personal license and have Pro, Desktop, and Online but not Enterprise. I was at an Electric Utility company so I was thinking I would like to get into that area or 911 but would not object to other areas. I worked in flood modeling for FEMA maps and used mainly desktop before. I am open to ideas from others if they know of other areas that are in greater need as I am draining funds and will not be able to do this indefinitely.Thanks.
