How many hours should i do quants everyday

It depends where you currently stand bro. Give 3-4 quant sectional mocks and see your score. If you are scoring above 75 - 80 percentile right now, you are doing a decent job and 1.5 to 2 hours of regular study should do for you. Otherwise, you have to increase the time depending upon your score. At the end of the day, quality matters a lot than quantity. So make sure whatever you are studying, you are putting your heart and soul into it. Feel free to connect with me if you need further assistance.
