I don't know which program you are in but I believe it is required. I am in the vet tech program and it is a requirement. It helps to give you hands on training and a lot of times the places you work with while doing them are able to help find you contacts who can later help find you work in that field. I strong recommend you complete it. I would call and verify that it is a requirement and if it is for your program how you can complete it while being pregnant or if you can postpone it until after you have your baby.
Best wishes with your studies!
