I am a student of delhi university. i have just started with my 1st year. Having read too many novels and literature, my language is decent. I want to know from where should i start, with quant. i have been a good student but still would like to brush up my concepts. and please no arun sharma, something i can complete with a year because i would join cat coaching from the next year, something light? and no ncert books 😛 or maybe if theres nothing left, then how do i start with arun sharma?
