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.

@hari.
So, can we write the centre address & paper name there below the line?
Because @ our centre they told us to write those details, compulsory!
for paper name space is sufficient but for center name(even school name) last year I wrote below line nothing happened I qualified for mains
As for as my knowledge some of my friends even for got to write center name,nothing happened brother,this is my third attempt. UPSC will not consider these mistakes.
thank you for the reply
kabhi kabhi ho log experienced hote hain unki bahut help mil jaati hai
jin logon ka pehli baar hai unhe toh darr lagta hi hai
thanx to people like you who come to our rescue

Q. 97 in Series(A)
when the RBI reduces the SLR by .50 basis point-
a. india GDP growth increases
b. FII may bring more capital
c. Banks may cut their lending rates
d. it may drastically reduce the liquidity to banking system
Now according to CL and vajiram key option (C) is correct…
but according to me if RBI reduce SLR then bank will have more money (=.5% of net time and fixed deposit ) to distribute as a loan so it will increase lending rate and this way bank will have .5% less liquidity……
so according to my knowledge answer should be (D)….any IDEA?
its Q. 97 in Series(D)
Hey guys.. I am getting 92.. SC candidate.. Any hope???
Dont worry if u have written below line….i have been doing this in all xams including upsc since 2013, never my answer book got rejected.
Sir, advice me how to calculate negative marks in upsc prelims 2015 by any examples
i have PH 1 category ,i am getting 78 marks in gs 1.
I like when people post such high marks…n still ask? Someday their own fear will sink them in ocean of pessimism
My score ranging between 124 – 112 with numerous answer keys .
But few correction to questions
1) About Babar( question is about introduction and not use ……. introduction means making it 1 st time)
Only statement correct- timrud dynasty
because-
Use of gun powder- https://en.m.wikipedia.org/wiki/Mahmud_Gawan is 1 st use gunpowder in 1411 itself and Babur though used but 100 year later
Dome and Arches- Bulbans dome 1 st true dome so no question of Babar to introduce
Couldn’t do well , able to score only 80 marks , I won’t qualify with this score.. Wrap up for 2016 I say
My score 120 (OBC)
Anyone with socio optional need short and good book for paper 2
Hi All,
I am getting around 95-100 marks(Gen Cat.) depending upon different answer keys.What are my chances?
Can anyone tell what are the predictions of cut-off from the different coaching institutes?
Q. No cyclone in south Atlantic and Pacific
Surface temp is no problem because sun shines overhead on tropic
ITCZ coriolis force is zero hence no cylnones ITCZ absence means good for cyclone
South of equator coriolis force is more
so after eliminating above I had to mark on absence of land
Upsc is only authentic
Q. Tax to GDP ratio decrease indicates
Slow growth – nope because if suppose government reduces tax rates can also reduce tax/gdp
Less equitable distribution — again nopes because if more people earning money but not coming in tax bracket = more equitable distribution
I think both wrong but
Only Upsc is correct
Very well replied sir..optimism
I am very late in starting preparation … only after june 15 ….was in pvt job .for last 6yr…left job now in notice period ..will be ready to dive for next time..I may get around 80..as gen category I am not eligible..but always allowed to see next yr (as i am 28yr old)….to serve country in a better way for next 3 decade of my life…
May all aspirant have best blessing of this bharat ma to live and die for nation honestly. ..
Can anyone please clarify 2 queries for me. Iam Aspirant of 2016
1. From where to prepare for science and technolgy.
2. How India Year Book will be useful and if helpful ,how to study it.
I have made one mistake in paper 1 OMR sheet. I filled center code in subject code and darkened the circle, when I realized the mistake talked to the invigilator, she asked to cross the wrong bubble and dark the correct bubble and correct the numeral also and she had signed near the corrections. She was assuring this will not make any difference be tension free and do the paper. Suppose my center code was 06, I had filled 06 in Subject code and darkened 0 and 6 bubble, later I changed the 6 to 1 and darkened the appropriate bubble, invigilator has signed near to this corrections. Apart from this my roll number and question series is correct, will my answer sheet will be evaluated?
please share if any body had done any such mistake in any exam and whether the paper was evaluated.
As per wazi ram answer I am getting 120 marks in paper I
@James… really hard to say if your paper will be evaluated or not….. machine check karta hai OMR. So technically for the machine… all sheets paper 1 & 2 are same. It will try to match the correct & wrong after applying 2 filter’s … 1st filter is subject code.. and second filter is set code ( a-b-c-d). Where there are 4.5L copies to be checked, it hard to imagine to image such an care would be given.. But if you get evaluated/selected, considering 120, you should be really thankful to fairness of UPSC.
Good Luck.
I don’t know how papers are really scanned and what are the crucial parameters. Some people say all paper 1 omrs will be scanned in one batch and paper 2 in another batch. So machine is not going to scan subject code, it’s pre decided that scanned is happening for paper 1 or paper 2. Some says that just the roll number and paper series matters, don’t know what to do, mine is last chance.
James your paper will be evaluated, most important thing is that you r roll number and question paper series is right, i made the same mistake in another exam and got through that, so dont worry and very good marks in paper 1, congrats…
@Ms, thanks a lot
James, don’t worry. Your paper will be definitely evaluated. In 2013, I had made the mistake of darkening wrong bubbles for my roll number in paper 2. The invigilator made me speak to the controller of examination for his centre who assured me that my paper will be definitely evaluated.
As a precautionary measure, mrunal sir suggested me to give an application to UPSC regarding my issue and requesting them to consider my paper for evaluation. I did the same and got a receiving of the application as well from UPSC. You can do the same as an added measure. My paper was evaluated and I qualified the prelims as well that year.
@Amit Kumar, I am outside of Delhi, please write whom to write the letter ? Can I email or send by post? Please explain
@Amit Kumar: Thanks for the idea of giving application. I Called to UPSC, the facilitation center guy told me whatever had happened give it in written and if you are out side send by fax. They said I can’t answer straight yes or no give in written to secretary they will decide. I have faxed the application and praying for the best.
sorry james it may hurt you but i must tell you the truth.your paper will not be checked,i had made the same mistake last time and my score in paper 2 did not come out this time.
@sumit: you made the subject code mistake or roll number one, you had corrected the subject code and counter signed by supervisor.
what can be concluded from the following instruction:
6. Candidates should note that any omission / mistake / discrepancy in encoding / filling in details in the OMR answer sheet, especially with regard to Roll Number and Test
Booklet Series Code, will render the answer sheet liable for rejection.
i m in, thanks UPSC for taking care of small mistaks
respected mrunal sir, plz help law material,really worried about it.
Discussion here is limited to civil services,anyone here please tell, what may be d safe score to qualify for forest service.(IFoS)

I have PH-1 category. It is my first attempt. Scoring 102-105 in GS paper 1. Paper- 2 qualified. Do i have enough score to enter into next stage??

no chance.
Sir I’m having hopes to clear prelims could u pls help me in selecting right materials for mains n my optional is geography
How is score of 85 to prepare for the next level????
i am preparing for UPSC. I have chosen law as optional subject. if you have law elated materials please give me or guide me.
i have also law contact me.+919415017934.but but medium is hindi.
Mrunal sir , i wil get 120+marks in 1st paper but in paper 2 i attemped only 39 qus. Out of 27/28 is correct by various answer key. To definetly achive a conclusion whether i qualify or not what shuld i do??
Correct ka total — 68 ban raha hai… galat ka -ve almost 9-10… matlab kya batau mere dost.
Total attempted 39, Assuming worse case 27 Correct then 12 Wrong. Then your marks come out as 57.5. If 28 correct then 60.83. In both case you don’t qualify buddy. Bad luck if that is the case
kya kiya mere bhai 4-5 aur kar lete bhai.bhagwan kare nikal jaaye tumhara.
Hey if I am expecting around 92, you think i will qualify for mains? General category
Looks tough. But you should start studying. If you qualify but you have not started then you will be kicking yourself. If you start studying and then don’t qualify, the studies don’t go anywhere, it will help you next year
