Dear all,

As we all know AMIE is the only platform which gives us opportunity for higher studies without disturbing our current work. To help all AMIEans we have created site which is open for discussion, polls, study material with that all AMIE related information is available.
We got lot of responses from u & we are very thankful to u as many peoples got solution of their doubts, we had one more “AMIE Students website” ,we got many responses from that site also. So we are planning to make it more useful website.
We have created Super membership, many people has sent us notes, question papers, study tips, video lectures, eBooks. As our site is loaded with study material, some newly registered people are not getting proper required material for the particular subject. We are planning all the material to be indexed & easily accessible for download. We have created group especially for the study notes (not for discussion) which will contain all study notes, video lectures, EBooks, Question papers.
