Hello Amith,
No, Akash institute do no sell it's module in the market.
However the students who have been to Akash sell there used modules.
You can buy those modules from the concerned person. You can explore the sites like olx and other buying and selling sites and can find the modules in which you are interested.
I hope this helps.

No, the institute do not sell it loosely. You can purachase it from the owned authority.
