I need help. I am 28 years old. Given this exam 4 times in the past 4 years. Written mains once. This year i have chosen a completely new optional subject and honestly, am not prepared for it. Having been an optimist so far, i think i could do it post prelims. However, the real trouble began a few days ago and i have been restless since. I am suddenly unsure of sitting for prelims this year. I feel my brain has reached some sort of saturation point and i can't seem to register any information. I think i could have easily chosen to not sit for the exam this year but does my age allow that now? I am unemployed and unsure.
