Apart from having free periods of time , mainly before the final exams .. no benefit at all .. i know some or alot of students become obsessed about that .. i used to see them "running" from course to course.. lol .. but surely some courses are worthy to be dumped .. by the way..some had three courses simultaneously..lol..

ok to make it short ..it is not a must ..don't worry.. i didn't skip or change the time of any course ..i took them one by one.. and wasn't much different.. just a couple of days they had b4 me in the final.. but i enjoyed the courses as much as i could..
