Rashmi Bansal has a great post about Bansal Classes, a coaching shop in Kota, Rajasthan, that helps a lot of students prepare for the Joint Entrance Examination of the IITs [link via DesiPundit]. Here's the clincher:
The secret of their success is 'pre selection'. Admission to Bansal classes is based on an entrance exam after class 10. There are 2 exams - the first is around April 15th, just after the 10th Boards. This exam is called 'Bullseye'.
The second entrance is in the first week of June. This exam is called 'Acme'. ...
Yes, there are 15 day crash courses to help you get into Bansal classes such as 'Garg classes'. Not only do they coach you for the Bansal test, they teach you 2-3chapters of their study material so you can score better in the first few weekly tests. Yup, it's one hell of a competitive environment. [Bold emphasis added by me]
