Software DevOps

I got accepted for retrain into 1D7 Z-shred and was looking to see if any of y’all could tell me about your experiences. What is tech school like? All I know is that it is in Keesler and that my RIP says it is 3 months. What bases are available? Should I do any self study before I get there? (Next to zero computer experience.) What kinds of things are there to do in Keesler? If y’all can think of anything else or any advice, it is greatly appreciated and more than welcome. Thank y’all in advance!
