Friends, I have taken pen drive course from Ajay Raj Singh and have secured 228 rank in RAS 2013 and appeared for IAS interview in April 2017. i feel that the course teaches good basics and is good for people with geography optional specially for people outside delhi who cannot take direct classes. He gives unlimited tests through email and online.I have also read all standard books. Since i was based in Mumbai, i had to go to delhi for tests once in a while. I just wanted to start this forum for giving info on geography to outside students. I took all tests from major institutes like vaji ram , vision ias ,chanakya and also took interview from these 3. Best of luck to all.
