September 16th, 2020       Civil Services Preparation

The first thing that comes to the mind of a UPSC CIVIL SERVICE aspirant soon after coming out of the
first half of the Prelims Examination is:

“How many marks am I going to get ? ”.

With much time left for the second paper of Prelims, the first thing we search over the internet, are the
answers which we have done just to make sure our position. The Internet gets flooded with examination
reviews from many coaching institutes. They come up with their answer keys.

These answer keys are the only documents which evaluate us on first hand. So before hovering into these
answer keys it is very important to follow the 2 steps
1. How much authenticity and credibility does the institute have?
2. These are not official answer keys. So any amount of marks you are getting must not be the base of
your final judgment regarding your preparation for the MAINS examination.

However, it has been found that a good, reliable institute provides 95% or more accurate answer keys.

How do we know?

We have collected samples of the answer keys provided by different coaching institutes/websites and checked it once
UPSC published their official answer keys. The result of our survey is astonishing.
Most of the answer keys from various institutes and web sites are found to be differing from the official answer keys
by around 10-15 questions. It may affect your first-hand evaluation to the tune of around 40-45 marks.

So the question is, which institute has the best UPSC Key?

During our survey, we have been able to check the answer keys of Aptiplus, Aptiplus, InsightsIAS, ShankarIAS,
VisionIAS, Mrunal, and Vajiram and Ravi against the official answer key of UPSC (2019).

The best 3 results we have got are following:

As you can see from the above table, the following are the notable features of our survey :
1. Among the Answer Keys we compared, APTIPLUS/IASGYAN answer key turned the most
accurate. Only 4% of the questions were wrong when compared with the Official UPSC Key.
2. InsightsIAS got 5 Questions wrong, while Shankar IAS got 7 Questions wrong against the official
UPSC key of Civil Services Preliminary Examination 2019.
3. VisionIAS too got 95 questions correct and 5 questions wrong just like InsightsIAS.
4. Mrunal’s Answer Key performance was also in this range.


do the answer keys differ from the official UPSC key

It definitely is a good question in the mind of an aspirant that,if these coaching institutes are not able to put
100% correct answer keys, what actually are they teaching.

o Lack of Knowledge: One reason for such is definitely, Lack of knowledge added with poor research.
o Different Sources and Interpretations: One needs to remember that UPSC CSE is not like any other
examination. Here, a question comes from different sources with different understandings and
conclusions, which may lead to completely different perspectives on the questions asked.

You can think like the relation between our Constitution and the Supreme Court. Although we have a single
written constitution available, interpretations of it vary from one bench to another. The perspectives get
changed with time, which in turn modifies our thoughts over our Constitution.

Likewise, an examination as dynamic as UPSC CSE, there is every reason for ambiguity and difference in
the answers from different sources. The questions with ambiguity will ultimately be answered when UPSC
publishes their answer keys.

So it is not good justice served when you criticize the coaching institutes who deliver right answer keys in
the range of 90% and above.


Aptiplus /IASGYAN every year, release our Answer Keys. Usually, we take 3-4 days’ time to come up with
our key (after sufficient research). Still, we want to convey to you that around 5% variation may be there
when compared to the official answer keys of UPSC.

This year, when the official answer key from UPSC came out, Aptiplus /IASGYAN Answer Key turned the
relatively reliable one with just a 4% difference with the official answer key.

The questions mentioned below were the ones our answers differed with UPSC Key. Here, we have used
SET A of the UPSC Prelims question paper.

(c) Both 1 and 2
(d) Neither 1 nor 2

Our Answer – A

Most UPSC coaching institutes’ key was the same with our answer keys with reference to the 3 questions
discussed above. However, as per the official Answer keys provided by UPSC gives a different answer to
the above questions.

How is the performance of our Prelims Answer Key in Previous Years?

Answer key News: Answer key Latest News and Headlines Today | Hindustan  Times

Like many other areas, we are continuously doing well when it comes to Prelims Answer keys. Our
credibility in this front is something we can proudly share with you. Our variations with the official key had
never exceeded more than 5% even in the previous years. The credit should definitely go to the fact that
we do thorough research before publishing our answer key.

Wait ! There is a Gray area here :

Sometimes aspirants tend to score marks more than the cut off as per the answer keys however, can’t clear
the prelims.


Suppose one aspirant has found that his/her answers to those 10 questions are correct, which by UPSC’s official keys
are wrong. Since one Correct answer contributes to 2 Marks, so he/she has calculated 20 marks for those answers.

However, on the other hand, negative 0.66 marks will be penalised if the answer keys are not correct.

So here , when the result comes, his/her marks will be Negative 6.6 in those questions. So his/her marks will differ
by 26.66 Marks, which itself is a big one as far as UPSC Prelims is concerned.


Whatever we have shared is based on our survey in the market. This however, is in no way to put other
coaching institutes in bad light.

Our objective behind this survey was solely to guide the aspirants and never to put the “BEST INSTITUTE”
tag on us by pulling others down. Analysis in any other year may show different results.

Our business ethics condemn such act and we refrain ourselves from any such practice. We, as an institute,
follow the objective of sustainability through honest and smart effort.

Although, these answer keys are very good when it comes to ready- made post exam analysis, these may not
be the ideal way to come into a solid conclusion as far as selection in UPSC CSE Prelims is concerned.

As far as ambiguity in answer keys are concerned, the key factor to judge an institute is to understand it’s
interpretation understanding of the UPSC CSE requirements.
