Sir, I passed class 10 in the year 2010 from W.B.S.E. This year I want to give the 12th final exam from nios; so I decided to register me for on demand exam for nios, I want to take admission in college on 2015 session; so if apply now; how much time I'll get before exam to prepare? & what type of syllabus I'll get ? I mean that syllabus of each subject will be given of 1 complete year or 6 months or e.t.c? & may I take bengali in language in case of on demand exam conducted by nios?
