I live in a remote City of Maharashtra Distt. Books availabilty for UPSC preparation is very rare. Though I have arranged many books for Geography Optional, yet not able to get the clear Idea about Coaching notes of Neetu Singh/Alok Ranjan/Shabbir Sir. Kindly suggest me whose notes are the best, so that I can arrange them from Delhi. Also suggest hand written notes are preferable or printed one ? What to buy ?
