Professor Changed Syllabus (ADDED 3 EXAMS)

I'm currently taking ECE 49595NLP with Dr. Siskind, and he sent an email 30 minutes ago saying that he's adding 3 exams to the course. The syllabus explicitly says "There will be no exams." The first exam is tomorrow, followed by another exam on Monday, and the last one on Wednesday. ARE WE FOR REAL? Is there any way I can dispute this bs?? If this is a joke, it's not funny bruh
