yup its tough.. but very fruitful if you stick at it. i dropped last yr and gave jee again. i dint even get a rank last yr. now i expect a good one. but if you want to take a drop, you should do only that. dont take admission anywhere. i suggest going to kota or even andhra pradesh and join a reputed institute. if u really want it, dont wory  about the cost of the things.. you can pay your parents back later.

consider it very seriously. one year means almost hell.. if you find a friend who has the same interest of taking a drop, the 2 of you do it together. but you will have to be very very serious about it becos if u lose.. then you will have nothing to fall back on.
