Is it wrong for me to ask to sit my exam in the exam hall?

My school mainly does triple science with a few students doing combined. All the triple science students sit their exam in the exam hall and for the first exam , the combined science students sat in the hall too - we just left earlier. The hall kind of makes me feel more pressure yk and it’s a good environment for me to focus in.
But for the next exam , I had to sit in one of the special rooms which is just a normal class room and sit the exam with the other 5-6 combined science students. I didn’t like it , mainly because I felt singled out but also kids were screaming , I could see the girl in front of me’s work on her laptop ,and not to mention the examiner was so slow and also you could literally cheat it was so unmonitored. I’m not sure how to ask to sit my exams in the hall without looking silly. Who do i even ask?
