I went through the MGMAT Advanced Quant
book and found the questions to be of a much higher difficulty- got about 50% of the practice set questions correct. I'm still not very clear with some of the questions I got wrong- some of the methods seem too lengthy to be solvable in 2 mins.
I was wondering, if solving just the Jeff Sackmann sets would suffice for getting a Q50 in quant?
I'm currently getting Q48-49, have another 2 weeks to go for my exam.
