Feeling guilty dropping this class

I just can’t do it because the professor teaches like 2x speed and likes to call on people. I know this might be a lame excuse but I’m one of those slow type of learners who prefer to go to tutoring sessions or ask online for help.

I’m upset because it’s a required course for my major and I would love to take it. But only if he’s not teaching it because the subject itself is already hard and his method of instruction scares me. Like I literally can’t sit in his class without my body shaking and my throat getting dry from anxiety of getting called on to answer questions during lecture.

I know I could just say “i don’t know. I’m not sure.” but still, he’s the type of teacher that has follow up questions like “what don’t you understand? Can you explain how you came up with that solution?” and I have what feels like performance anxiety sounding stupid in front of 30+ people in the room.

I’m trying to get as much as I can to prepare to drop and retake it this summer with a different professor, but I wanted to vent because it feels like losing a battle.
