I would definitely reach out to your professor(s) about it. Most colleges have a disability program (and yes, stutters are typically included in that) so I would see if they can accommodate for you. I know I found out about my disability program way too late, but I did take my public speaking class online and made my first introduction speech about having a stutter (it really sells it when you’re talking about it while struggling with blocks and all that fun stuff). The professor was super understanding after that. I feel like as long as they know you have it, they grade you based on how organised it was, instead of how it was delivered.
