Hi.. i have given cat 1 and cat 2 and scored 620 on the first and 550 on the second .... my math on cat 1 was 49 and 42 on cat2... i was wondering if you can explain the dip.... the tests were given a week apart and i did leave practicing ques... also someone told me that cos a i got 49 on my 1st test thats y my questions were tougher on the 2nd cos... is that fact or myth?
i have also been told that the 4th RC holds no value on the gmat and there is no point wasting time on it.. i should just mark all of them and move on to try and get max CR and SC rite.. is that a myth or a fact
