problem im facing in reasning is , i think im taking too much stress while giving mock and if not able to solve one set then i end up not solving any set.. and the moment i solve it after mock i can able to do each questin in around 15-18 min each. help!!!

before mock just say to yourself i am capable of solving and at the back always know that questions can be solved in last 15 mins so if in case not able to solve early , there is still chance

dude i was also facing same issue but one thing help for me is that start revise all mocks again with personal timer of 120 min and then whenever you give live mock lets say start with solve one rc then slowly increase with maintain accuracy hope it helps BONUS - start mock with most positive attitude you ever have
