Dont want to go for live classes, to surprise everyone i want to preapare  secretly. But i am Confused, Whether dvds sold on olx & quikr are reliable, claiming latest hd quality classes, at rs 500 per subject. Dont want to be a fool. So asking before you all. Or you can recommend me for buying so, reply asap..
