MUMBAI: Open category students could be left with no seats in junior colleges which are attached to schools, with the state having issued notifications to implement the two new quotas - 16% for Marathas and 10% for economically weaker sections (EWS) from the non-reserved category. For, the share of reserved seats in such colleges would go up to 103%.Under the online admission process for first year junior college (FYJC), 330 of the 810 junior colleges have attached schools. Of these, the minority ones will remain unaffected by the new quotas.The school education department is looking at ways to deal with the situation. An official said they will have to be ready with the seat matrix with and without the 16% Maratha reservation. "We are considering reduction of the in-house quota to 10%. This will leave at least 7% seats for open category students in junior colleges attached to schools," said the official.Junior colleges which have attached schools have to set aside 20% seats for in-house students, over and above the 52% so far for reservations (such as SC , ST , OBC, NT, etc) and 5% for management quota. The current reservation, therefore, is 77%. With the state implementing the Maratha and EWS quotas of 16% and 10% respectively, the total reservation would go up to 103%.Some junior colleges with attached schools are Sathaye, Dahanukar and Bhavan's, in the suburbs. The online admission process for FYJC covers areas from Churchgate to Mira Road, CST to Badlapur and CST to Panvel (urban).As the Maratha quota has been challenged in court, an official from the school education department said they will have to be ready with the seat matrix with and without the 16% Maratha reservation. "The EWS quota of 10% anyway has to be implemented. But the Maratha quota is challenged in court. We cannot wait for the outcome of the case as it may delay admissions later," said the official, adding the plan is still under consideration.Since Mumbai region deputy director's office conducts centralised online admissions for FYJC, the department will have to be prepared with all seat matrices. "Colleges have to start registering for the online process soon. More new colleges are likely to come up in the region too. We will have to be prepared," an official said.Open category seats in non-minority colleges (without attached schools) such as Ramnarian Ruia, DG Ruparel, Sydenham and Podar colleges will also shrink in the coming academic year. Currently, these colleges follow 52% and 5% management reservations. With the EWS and Maratha quotas, open category seats will be down to 17%. There are over 200 non-minority colleges in the region. Top minority colleges such as St Xavier's, Jai Hind , HR, KC, Mithibai and NM will remain unaffected by the quotas.The new reservations will not only reduce the pool of seats in the open category in junior colleges, they would also have an impact on degree college admissions. A principal from a non-minority college said universities too will have to follow the state and Central government reservations. A university official said our notifications are usually released in May, when the admission process begins.
