Apple products and programs for poor economic undergraduates

Apple offers discounts on Apple products through the education store for students and teachers in education institutions enrolled in the program.

Apple has set discounts for post secondary students, and teachers/faculty of all levels. Apple also provides discounts to schools that purchase in bulk. If none of these work for you, you may need an authorized reseller like CDW to assist. If those discounts still do not put the devices in your price range, you may need to look into other options.

You would need to contact Apple directly and see if they offer something in India: Education - Higher Education - Apple (IN)
