The philosophy of our Test Series has been to bring it closer to the actual exam in terms of both toughness and format. We try to ensure that the standard of questions is continuously raised.

Here are 5 ways how we do it. 

1. Evidence-based question making

The questions are not framed according to the whims and fancies of the question-makers. They have to provide objective evidence to the supervisory team about the relevance of the question and why it has a higher probability of being asked in the actual exam. They have to prove that a similar question has been asked previously in the Prelims exam.

We are putting in conscious effort to ensure more questions are asked on themes that UPSC considers important. At the same time, we try to ignore those themes that UPSC has been ignoring. List of examples presented at the end.

2. Question-Types for ensuring quality – Judging the quality of any TS is very subjective. While some will say its great, others will say its quality has decreased over time. That is why we have introduced the concept of Question-Types. They ensure consistency in quality. How? We have explained that in the end.

3. Tikdams for mastering the art of intelligent guessing – Tikdam Technique is an innovation by Dr. V(AIR 20) and has helped students gain additional marks. Our TS is the only TS that puts a conscious effort to build student’s risk-taking appetite.

In the lecture below, Sajal Sir provides a comprehensive explanation to the Tikdam Technique with 2017 UPSC Prelims Exam.

4. Subject and sub-subject Level Tagging – These tags ensure that we remain close to the exam. At the same time, it will help you understand the importance of themes and revise other questions from them.

5. Dedicated monthly CA Tests and Full-Length Tests for revision – Exclusive focus on Current Affairs(CA) by having dedicated monthly CA tests helps students understand their level of proficiency in their current affairs preparation. Full-length tests ensure a rock solid revision. 



Besides the above, we are the only Test-series that offers the following –

1. Comprehensive program w/ Advanced Lecture Series(ALS)

Our TS is a full-fledged course in itself! We provide over 60 hours of Video Lectures. Our questions with detailed explanation are a course in themselves. Effective for both,  beginners and advanced students.

2. Telegram Groups

Moderated by Toppers and Mentors. Mentorship is taken to a whole new level. You will be helped at every step of the way.

3. Civilsdaily Monthly Magazines

CD’s Monthly Magazines are a brand in themselves and have been a preference of Toppers for years. Currently, we are rolling out the following magazines in the Monthly Magazine package.

1. News + PIB (without oped)
2. Op-eds

4. Govt. Schemes in News

What are Questions types 

Wherever applicable, we will try to stick to the format decided below. It standardizes questions to a decent extent.

A. Consolidation Questions
These questions consolidate information on a key theme that is spread across different topics to help you see concepts holistically and also aid retention.
Eg. Consider this question. You would not have studied all the ‘Majorities’ together but under separate topics. This question will help you understand the concept in entirety.

Consider the following questions on the types of Majority
1. Special Majority of not less than 2/3 of the Members present and voting is required in the passage of a resolution under Art. 249 and Art. 312ONLY.
2. Impeachment of the President requires Not less than 2/3 of the Members present and voting along with Majority of the Total Strength of the House.

Which of the statements given above is/are correct?

Explanation – A very detailed account of the types of Majority is given here
Statement 1 is correct despite having ‘ONLY’ in it.

B. Comparative Questions
Comparative questions help you understand the relative differences between related topics. Consider the question below. Instead of asking a question on HC or SC separately, we have clubbed it together.

Consider the following statements with respect to the appointment of judges of High Court & Supreme Court
1. The minimum qualifications prescribed in the Constitution is same for judges of HC & SC.
2. While SC judges are appointed by the President, HC judges are appointed by the SC.
Which of the following is/are incorrect?
a) 1 only
b) 2 only
c) Both 1 and 2
d) None

Explanation – 3 qualifications are common to both judges of HC and SC
1. Citizen of India
2. Judge of HC for 5 years
3. Advocate in HC for 10 years
In case of judges of SC, there is an additional qualification – If he/she is a distinguished Jurist in the opinion of the President. Judges of HC are also appointed by the President. The controversy around appointments has been in news very frequently. Please read –

C. Interactive Questions
These questions will ask you to go through a concept/related concepts and reply back with comments. This will help you re-visit the entire concept rather than simply answer one specific aspect of the topic.

Eg., consider the following question –
The conversion of Ammonia (NH3) to nitrite (NO2-) and then to nitrates (NO3-) is called

a) Nitrification
b) Ammonification
c) Assimilation
d) Denitrification
Answer A

In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Ammonia is oxidized to form nitrites by bacteria such as Nitrosomonas species. Nitrates are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants.
Make a note of all the processes involved in the Nitrogen Cycle – nitrogen fixation, assimilation, ammonification, nitrification, and denitrification process.
Leave their definitions/organisms involved in the comments.

D. Star-marked/special questions
These are advanced questions that are not from standard sources but relevant for the exam. These questions will help you build additional knowledge without going through specialized books.
Eg. Questions on books by freedom-fighters, News not covered by the Hindu, IE, PIB but of very high importance in world affairs.

Besides these, questions indirectly related to CA will also be asked. 



Do I need to join a TS for prelims at all?

Trend changes since 2017 clearly indicate that the prelims exam has become more and more unpredictable. In such a scenario, a prelims TS is the only program that can help you assess how your preparation going.

Besides a few questions that are directly asked from TS, it helps in developing a good understanding of how to prepare/what to prepare/what to prioritize and so on.

In today’s hyper-competitive exam scenario, it’s almost impossible to clear the exam without a good TS in hand.
