I'll answer the last point you asked first. There is no limit. There are, you know, recently, this last academic session, which started there's one deafblind boy from Nasik, who got admission in IIT Nagpur. So, there is there is no limit to that, when it comes to, you know, kind of education available, it depends on the child's residual abilities, if the child has some vision, we need to utilize as much as possible, or some hearing, we need to utilize that as well. Fortunately, it's a blessing that not all deaf blind people are totally deaf and totally blind. That number is you know, quite small. And that is one reason that most of the deafblind children do very well in inclusive setups, and there are some who are, I would say, not very highly functional because of their conditions, they do quite well in a special school. So, when I say a special school, these are schools set up mainly either for the deaf or for the blind, where a deaf blind unit sets in very well, because the communication is a major key for these children. So, for giving them you know, starting education is all through touch to begin with, and they have a calendar box system. So, like we have a period where you know, first period is prayer, second period is probably physical education, third period is language the fourth period is mathematics and this and that, all those kinds of things we have and we carry books like that. For deaf blind child, it is physical so there are calendar boxes. And and the teacher starts with picking up a object which you know, indicates that particular period. For prayer, there might be a map because all of them will sit together in the map. For time when they are going for music, they will be a small musical instrument or something. If there is a physical education, there might be a small piece of toggle, or for mathematics... all the objects which are used, they're there in the calendar box, and the child with the teacher proactively picks up and the teacher explains what it is and the child also slowly gets to understand that when I pick up a musical instrument, it is time for music. So once they finish that activity, they put the object back into the box so that it indicates finished. This is a simple routine that they follow to begin with, till they are at a stage where they can understand how days of the week work, how months work, seasons work. So all starts with a very simple kind of calander system.
