When I answer questions, I can't even say a single word properly. So, they can't understand what I'm saying. Also, I speak pretty fast. This adds to my problem even more. My stuttering is albeit different everytime. Sometimes, there's a blockage on every first word of sentence. On bad days, I can't even speak up simple words, for example in last viva, I had to say, "Smith Scale", but I could only managed to say, "S-S-S-S", then I stopped. No, they don't know I stutter. Because I din't speak much and don't ask any questions. I guess, they think I'm nervous, when I'm unable to speak up properly.
