I am using Lightroom and Photoshop cs6 education edition.
You need to to adobe india store and select student and teacher edition.
It will show PS CS6 for 4090/- and complete CS6 suite for 12xxx/- INR.
Add to cart and proceed for checkout.
On payment completion you will be asked to upload valid education institute id card image (JPEG / PDF).
Point to ponder : Id card must have valid upto (expiration date). To be on safer side scan and put both sides of id card and also last marsheet image on single pdf file and upload.
On completion of order you will get email of confirmation.
On 2/3 days time you will get second email with product key and download links
Enjoy its one of the best way to enjoy legal licensed software.
