In kaplan a prof told me , dont care your score in practice test , he said just do questions and questions , everytime u make a mistake u will learn new things and u will learn 5 things from a ques as it has description of 5 options ... so do 40 questions a day u will learn 200 things per day ..... So just do question and simultaneously read book with every questions , for 40 ques + reading book will take 6 - 8 hours ... i Liked his advice and following that ...... I have my ck exam in June 2010 ... but yes study pattern varies person to person .....
