And if the blind cannot find a student willing to take the extra time to record or read the daily lessons, this is also then not possible. Now consider the sighted. With many bookshops and libraries all over the major and even smaller cities throughout Vietnam in which they can find very easily any material they want, the sighted can read for free and buy the books they need to concentrate on. Then, on their own and at any time they desire, the sighted can read and study as time permits. Time is yet another factor to be considered.
All students have a limited amount of time in which to read and prepare their lessons.
The time for all students to prepare a lesson is very short, rarely more than a day or two. In a school for the sighted, the blind are not given extra time to prepare their lessons, even if they were to ask for it. It is a certainty that the blind do need extra time. There is no extra time given to the blind for the lengthy and difficult process of transcribing a lesson into Braille. If a blind student has a very good helper, the sighted helper will arrange his or her schedule to allow the two to meet on a regular time each day.
