I cant do this anymore! From 63 in VARC to 29. And consistent score between 25 and 40 in DILR. VARC is going down day by day. For every test I take, it feels like I have lost the ability to comprehend Passage. I am drained. I don't have energy to keep my self motivated. I feel wasted. From 98.8 %ile in SIMCAT's to 89-92%ile is really really painful. No matter how many sectional tests I take, I am just unable to improve my scores. This is my second CAT attempt. In 2016 I had 96.5%ile.. and the way mocks are going.. i feel enervated. I have sacrificed way too much for this CAT. And watching people's score in SIMCAT groups exacerbates my morale.. I tell my self so many times, not to give up, but there is so much expectation about percentiles that it is killing me deep down. 


I don't even know if I can take a break, given CAT is only a month away. 


If anyone has gone through such phase, kindly help.
