Hello RKORyder, sounds like anxiety to me >>> Anxiety, Panic and Phobia Center - Psych Central Like a performance anxiety, when you are put on the spot you find you can't think straight to come up with the answers. Then you beat yourself up for being stupid and it becomes a vicious circle. Tests in particular do that to me and I become instantly dumb.

Let your teachers know if you have mental health issues so that they can make accommodations for you. Practice relaxation techniques, enquire and see if there is a counselling service and talk to your doctor about any medications that may help.
