Industrial Engineering Advice

I'm going to be a junior in IE in the fall, and I want to know how to make the most out of my professional and personal experience at Purdue. I've also had a pretty rough year, and pretty much lost all my friends from freshman year and struggled to make new ones. But I'm motivated to have a better college experience next year. I'm interested on the manufacturing side of things, but I'm open to try out anything! I would appreciate any advice on classes, clubs (both professional and social) to join, and oppurtunities/events to check out! Thank you!
