Above is the current status of my prep. I haven't met any person prepping for UPSC offline. I stay far from ORN hence joined a library nearby my home but most of the peers here are preparing for CGL. I want some guidance and hence decided to post it here. Please go through it and guide me with the following questions:

1. For IR, security, disaster management, post independence, world history - what sources should I follow (I am in a dilemma that at this point of time doing any courses will help or should I refer some books). For IR, I am just following current affairs but I am skeptical if it will suffice content for ans writing. Please suggest if I should do any course especially for IR
2. What should be the order of completion of subjects considering I need to finish mains prep (including some bit of ans writing by December)? What should be the ideal deadline for each (plz give a timeline) At this point of time I have these things on plate:
   1. Completing ethics, economics is on priority. Right now focusing on finishing anthropology.
   2. Revise the already completed courses
   3. Current affairs
   4. Start ans writing, essays
   5. Finish off less priority subjects like post independence
3. I am confused about which language to pick up as mentioned in doc. Should I pick telugu bcoz I have good vocab but poor grammar & spellings(which I need to learn) or hindi bcoz I am okaish with grammar but poor in vocab
4. Current affairs - will monthly magazines of vision be enough for pre & mains? Should I invest time in editorials of newspapers for using keywords in ans/essays - will it be worth considering the time left?
5. When should I start with essay writing?
6. For anthropology - will following good journals help? What is the ROI? Also should I keep noting down anthro related news or just pick some coaching's compilation at the end?

If there are some suggestions for me, plz feel free to drop in! It has been a hard time finding a good senior to ask these questions...

Only serious comments plz
