ACCUPLACER Engineering worries

Hello, I am going to be attending University of Michigan - Dearborn next year as I am a senior in HS at the moment. I plan on majoring in some form of Engineering but the thing is I am kinda weak in Math. The placement exam I will be taking is called ACCUPLACER and it tests many things such as arithmetic, elementry algebra, college algebra, and so on. Since I am going into Engineering, I am hoping to place in Calculus 1 so I can start going at my degree right from the start and not take any remedial classes. My real question is, what if I do bad in the ACCUPLACER test? What is the worst case scenario? Will I be put in a really low math class and have to build up or is there a limit to how low of a class I can place in if i am going into engineering? I would really appreciate some feedback. Thanks!

Worst case is having to start in lower level math courses. This will probably delay graduation.
