UPSC had conducted Civil service and Forest service (combined) preliminary exam aka CSAT-2015, on 23th August 2014. Here are the scanned copies of Booklet no.”B” for both paper 1 (GS) and Paper 2 (Aptitude):
Detailed Analysis and Topicwise Answerkeys with explanations (for all sets), coming soon.
- You’re most welcome to provide your inputs, answers, observation, analysis and experience in the comments below.
- If you want to discuss then discuss MCQs, (and not cut-offs.) Everyone who had prepared sincerely, and did not risk too much negative marking, he/she has a fair chance of clearing prelims.
- Internet user sample size too short to make any predictions. So don’t lose blood pressure, if Mr.X, Y or Z says he ticked more MCQs than you.

hi guys,,
Have doubt on currency convertability,,,I guess answer should be ‘b’.But all keys suggesting ‘c’.
the emphasis should be on the market or controlled rather than freely permitting conversion or not.
Ncert 11 class book suggests convertability to both gold and other currency.In such case option ‘a’,may also be correct..
Please clarify my doubt
Hi ,
The question on convertibility,,answer can be ‘b’ also..convertibility allows the rupee value to be fixed by market.
Please comment on this.
you are getting confused with exchange rate
that was before 1960 then it has changed

Hoga ya nahi ?
MUSHLIK HAI BHAI….TUMSE NA HO PAYEGA!!!
Accept it or not, the level of civil service has been going down — even becoming similar to state PSCs . It was best for three years — 11,12 and 13 and then it became like rote learning , facts etc. Even arts and culture was way better for three mentioned years. Asking reason and analysis should be the basis for any exam.
Sir, please wake up from hibernation. Please start Mains preparation
My score according to various keys
Paper 1 125-130
Paper 2 165-175
Applied for both IFoS and civil services. Optional-zoology (botany too for IFoS)
I doubt that I am clearing IFoS cutoff, still starting preparation for it.
Anyone with the same optional? Any idea about test series for these subjects and essay? Joining vision for GS.
Venus u r sure shot clearing the exam. For GS do not rely on any particular academy. just stick to the syllabus and newspapers, few magazines (with selected topics only).Try to give as many tests for MAINS as possible just to make speed and writing suitable answers. For GS u may go to VISION but for GS-4 (Ethics) also refer SYNERGY (M.K. Mohanty), c y a . good luck
I request Mrunal.org to start uploading posts for mains. Please also inform about the area wise coverage of each paper in advance so that many like me can prepare their own strategy

please do check if somebody who has given the paper on 9th august 2015 morning shift is also facing the same issue and let me inform as soon as possible
Yes … I checked .. There are around 4 or 5 outright wrong answers provided by SSC for 9th August 2015 Morning Slot. I have already challenged those answers in the prescribed format provided by the Commission. I suggest you do the same.

Sir, when you will start economy lectures for 2015-16 for the next paper 2016..
@ please help me : a bit of advise from me – Don’t worry. I have seen similar story in my family. We r also from a middle class family. My younger sister completed her M Sc in 2010. In 2011 she could somehow convince us to prepare for Civil. Parents were reluctant at beginning. She was also given a two year target. Could not clear pre in 1st 2 attempts. Huge pressure (just like you). She was also hopeless. Still kept working hard. Finally in nex attempt not only pre, she cleared all steps i.e finally recommended and is now IRTS probationer. Is’nt your story similar, so don’t give up. Identify your weak areas – improve them, identify your strong areas – polish them, take guidance from right people, you may succeed. And the same oarents & family who are mounting pressure will feel proud of you, like my parents who are more proud of their daughter than the two sons. All the best.
