Be ware of this Guy, Anil Dubey. He will excite you that he will teach you techniques, which can get you higher band score but I realized that that was not the case. All he can offer is given in his book "IELTS MADE EASY" which is indeed a good book. There is nothing new he can offer you in his training.
I suggest, t buy the book and practice throughly ! there is no short-cut method to get higher band score.
Combridge series books are good resource for practice.
