Are GregMat Quants questions difficult , because when I solve the Manhattan book and then solve the GregMat Questions , the difficult doubles ?
I would describe the Manhattan questions as more straightforward, which makes them good for building your quant skills through repetition.
I find the GregMat questions to be “trickier”—they seem to be more geared toward encouraging the utilization of a range of foundational concepts to solve complex questions. Sometimes I felt like solving a couple of the GregMat problems was more exhausting than completing an entire chapter in the Manhattan book. Think of this as a good thing, since solving the GregMat questions encourages creativity and attunes you to details.
