Hello,

To be true, YES. Today as we know that there is intense competition all over the world, and the companies want excellence. So there are many companies today, especially the MNC's and the BPO's that actually do not even consider students who have dropped a year for preparations of entrance examinations. I know it sounds ridiculous but it is true.

However, you need not worry about it, because there are plenty other companies which do not have such a silly condition. Infact they just aim for excellent students, the hard working ones who are ready to sweat it out.
So, if you  drop 2 year, all i suggest is that, work hard, and make proper utilization of it, so that it will add to your benefit in future!!

Good Luck!!
