My school thinks the faster you answer and talk the more you’re prepared, when I was asked a rather difficult question in 9th grade I thought for 3 seconds and the teacher called someone else, it wasn’t about blocking, I had to think for 3 seconds and I had the correct answer but apparently they were training me for a possible working environment where I don’t have 3 seconds to think… now imagine how stressful it would be having oral exams specifically with this teacher while having speech blocks?
