How to attempt quant ans with speed. I am abel to do the sums when there is no limit. But i unable to attempt more that 12 question in quant.

Hi Deviram Kondaveti,
Speed increases with practice. Try to practice as many questions as possible especially from Arithmetic, Algebra and Geometry. While attempting a mock/sectional, finish the easier questions first, medium next and hard later. This way you don't get stuck at one difficult question. Hope this helps!
