ESRI has created hundreds of web courses and other training materials to help you learn ArcGIS and other ESRI products. ESRI web courses are: 

• available for free to current MIT students, staff, and faculty
• online
• can be started and stopped at one's convenience

If you are a member of the MIT Community, create an ArcGIS Online account and then use that login for ESRI training. Ask if you need suggestions for courses!

**Note that some training materials are not available for free, such as in-person training, certification prep, books, etc.
