It’s nice to have a conversation with your teacher if you want to have the practice of reading out loud. Let them know beforehand if they don’t already. If you want shorter paragraphs/pages I’m sure they wouldn’t have an issue with that, or doing a popcorn reading once you have had enough of it & are struggling in that moment. It’s also nice to have a conversation with your peers, you’re in senior year so I’m assuming most of your peers already know you have a stutter, but it may help to just introduce yourself and say you have a stutter and then explaining that sometimes you get stuck and take a little more time than other people but you’ll get through it. I wish you luck!! You have so much more confidence than me, and i would literally cry to my teachers in school so I didn’t have to read or present! You’ll get through it just fine :)
