Hi,
How to add 21C1 + 21C2 + ---- + 21C21
Need a valuable suggestion. Well, i have to prepare for my quant section. I have never taken cat before and will be taking this year for the first time. I have all the study materials of Career Launcher. So just wanted to know what would be the best and sufficed way to prepare for quant, whether by solving the whole study material or i will have to practise from Arun Sharma as well? Is it not sufficient if i solve questions only (and every question) from study material only.
Kindly help me Puys.
Thanks in advance. Cheers 😃
