Advice
When you are at a co-op, you are there to learn. That should be your number one goal, and your company's number one goal. So, use that opportunity to ask literally any question on your mind! "How does that machine work?", "where does this assembly go from here?" "How does welding even work?". People love to tell others about what they do, and a work environment, especially a factory, is something you can never read about in textbooks. You'll have about 4 months or so in an internship, use it the absolute best you can.
