hello everybody. i'm varatharaj doing pre final year in mechanical engineering in coimbatore(tamilnadu).Right from the day i know about cat i started dreaming being an IIM er! MBA is my passion. im preparing for CAT 2013. As i was from a lower middle class background i cant afford to pay the coaching class fee. now iam preparing for CAT using the books from my college library.
but those books are really confusing and deviated from the actual CAT questions.i dont have a pc too. so i cant refer any online materials. i spend 4 hours daily for preparing CAT. my friend advised me that 4 hours of such preparations=1 hour of preparation by using standard materials like TIME,IMS. i went to TIME and ask them whether i can get the materials alone for a cheaper price. they said they will provide material only along with a course. and that course costs 20000! i was heart broken! i desperately need some standard books. i would be greatly thankful if someone is will to donate extra materials or old materials! PG is my only hope. so please help me! thank you all
