First off, most of us understand how terrible you feel in the first days with tinnitus. It is such an alien sound and your brain will zoom in on it all the time. We had been there so we know. So the best thing is to get some masking going, and try to see your doctor to see if you need some meds to help you temporarily. Don't worry too much about T as it may fade or disappear for the newer sufferer. Focus on your exam to get it over first. You have all the time after that to deal with T. Most people will get better with T over time and with a good attitude. You can rush T to be better overnight so don't waste time and energy on that. Focus on the study as much as you can, using music or nature sounds to mask it if needed to get your concentration away from T. All the best to you and your exam.
