25% increase in number of girls from Bombay zone for IIT-JEE There are far more girls set to appear for the Indian Institute of Technology Joint Entrance Exam (IIT-JEE) in the Bombay zone in April 2012 than before. The number of applications by girls has increased by nearly 25% compared to last year. The Bombay zone includes Maharashtra, Goa, This year, girls account for nearly 27% of the total candidates applying, with around 20,300 girls from among 76,600 candidates. The IITs have been constantly trying to address the skewed male-female ratio at the IITs. “This is a significant increase,” said AV Mahajan, chairperson for JEE 2012, Bombay zone. “One reason for this could be that it was free for girls to apply online this year as well as cheaper to apply offline as compared to male applicants.” Two IT-BHU students to start entrepreneurship club for school students VARANASI: When they cracked IIT- JEE two years ago, getting attractive jobs in top IT companies was their dream. Now, they want to promote entrepreneurial skills in young school children (Class X onwards) by establishing entrepreneurship club for schools. Bhanu Swami and Varun Agrawal, B Tech (III) students of electrical engineering of Institute of Technology, Banaras Hindu University (IT-BHU), are on their way to launch country's first entrepreneurship club targeting students (Class X onwards). The initiative not only aims at tapping and promoting entrepreneurial skills in young students, but also promises to turn these students into entrepreneurs. This way they would become job providers rather than job seekers. Akash 2 tablet to be launched by April 2012: Govt. The government has expressed confidence it will be successful in bringing out the improved version of the Aakash tablet by April this year. The Aakash 2 is likely to have several improved specifications such as elongated battery life and faster processor. The government has been striving hard to make its Aakash project successful. The device, which is also touted as the world's cheapest tablet, faced harsh criticism from several quarters for its poor quality and dismal features. IIT Rajasthan, which developed the prototype of the device along with Data Wind, found a series of faults in the device, prompting the government to reconsider extension of the LC to the Canadian company. Under pressure to provide better endowed low-cost device, the government has now its turned attention to the Aakash 2, which is likely to come at the same price tag of the original Aakash. HRD Minister Kapil Sibal has said that the government will be looking for more manufacturers to manufacture the Aakash 2 tablets, attributing the massive demand for the move. “We want to make sure that the upgraded product caters to the need of the customers... We have involved ITI in order to upgrade it... We will be able to bring in Aakash-II by April," Kapil Sibal said. Last week media reports had hinted that the government might shelve its Aakash project in view of the harsh criticism from most quarters. The reports were triggered by DataWind's opposition to certain test criteria suggested by the IIT.
