Comprehensive passage was little bit easy…remaining Barron’s will help u…
Next was analytical..see frnds..this time..both previous papers and R.S.Agarwal dint helped me…questions were totally talent based..3 questions were too long..even I dint read them..juz guessed…there were 15 questions…
2 questions were on divisibility…say…
A number when divides with 9, 8, 5, 3 leaves remainder 5,3,6,0..wat is da number…u can do this simply by verifying the options…another was also the same type…
One was on Permutation and combinations…my view is that..to be good in all mathematics basics n general thinking…so dat it would become easy…
Next was the most tuff one of the exam..analytical…god…Iam from biomedical engineering stream..n all question are from java..oracle..unix..only one question was from C n other one from C++ ..
20 questions were asked..gud news is that…wipro management said that…there will be lower cut-of for non-it branches…but this was accepted by them prior to the exam..we informed about this to wipro..on aug 1st…
