Hello! I'm Josh and this is my first forum post ever. I'm currently employed as a Field Service Engineer for a lithography company in the semiconductor industry. I learned all of my electrical and troubleshooting skills through the US Navy, and I plan on going to the University of Maryland next year to study mechanical engineering. As for now Iâ€™m just trying to learn as much as I can to get a jumpstart on school. So if any of you have suggestions on how to teach yourself single variable calc, the basics of thermodynamics, or any other topics please let me knowâ€¦ any help is much appreciated.
