The camps help the young women to catch up on lessons they may have missed so they get the most out of their time when they return to school.
The venture is one of many being supported by UK-based churches' development agency Christian Aid, through its Present Aid schemes.
For £96, supporters are being encouraged to finance a teacher's salary for a term through a charity gift subscription.
Other possibilities include providing nutritious meals for school children in the Indian sub-continent.
Christian Aid hopes that in spite of the economic recession, people committed to working for the alleviatiuon and elimination of poverty will use opportunities like this to give a different kind of Christmas present on behalf of others.
Other recent additions to the Present Aid virtual charity gifts shop include chickens and flood kits for a disaster.
Meanwhile, Astha, from Digboi, has also organized medical camps for disabled persons. In Assam there are four such centres and in Dibrugarh a further one.
