Hi, All these feeling are completely natural and we say as exam stress. You know if you completely study but you have stress, the neurotransmitter in your brain and between you neurons, can't be completed due to less hormones from your brain. It means at the time of stress, our brain, focus to reduce stress other than working for remembering all the materials in the mind. So hormones are less, and neurotransmitter can not be happened, so you never remember the material of your study very well. The only thing is that, just have meditation, relaxation before the exam, don't think about the results and marks, just believe yourself as you studied hard and don't think about the other's judgement... With all these changes, you can have a good time at the exam an you can remember all the materials. Do take care.
