UPSC IAS prelims is a high voltage pressure exam, and with the mercury rising, it would be very difficult to remain calm during the paper. The candidates must read the questions correctly. UPSC designs the question in such a manner that it is not easy to understand in one go. Each question requires the following steps.
- Reading the question correctly
- Reading the answer option correctly
- Deciding on the correct option
- Marking the answer correctly on the OMR sheet.
The marking is very important because the candidates need to mark the answer with a ball pen, and once marked, it is very difficult to change the answer. On marking more than one option, that answer will be counted as a wrong answer, even if one answer is the correct answer.

UPSC IAS Prelims 2025: Do not panic if you can’t answer initially
The candidates should attempt the paper in rounds. In the first round, read the question and mark the answer only when you know the correct answer.
In the second round, mark the answers where they can resort to intelligent guesses. Do not waste time on one question only and keep moving to keep a tab on the time.
Naturally, at least one or two questions will go wrong due to the unforced manual error of not reading the ‘not’ word in the IAS question or not analysing the answer marked.

There is no need to panic in case the candidate cannot answer ten or more questions. It is natural. The IAS prelims questions are so designed that most of the candidates know the answers to only 25 per cent of the General Studies paper I.
The candidates who have extensively prepared for the IAS prelims can mark the answers to around 40 per cent of the questions correctly. But it is very difficult to mark the answer to more than 50 per cent of questions without any doubt coming to mind.
UPSC IAS Prelims 2025: Practising with Previous Year Papers
The candidates must practise with mock tests and previous years' IAS question papers to train their minds in reading and understanding the language of the UPSC questions in a better and more time-efficient way. It will help them during the actual examination.
IAS Prelims 2025: Role of Guessing
Firstly we would suggest avoiding guessing in the paper. But it is evident that to increase the number of attempts in the paper, all the candidates resort to guessing. The candidates should not wildly guess the answer if they do not know anything about the answer. But calculated and intelligent guessing plays a very important role in the IAS prelims exam. It only comes with extensive preparation and studying all the aspects of the topic.
Elimination Method
Elimination method is a part of intelligent guessing. The candidates should carefully read the question and eliminate the answer options which they feel are completely incorrect. They should only mark the answer if they can eliminate at least two answer options. This will make the probability of marking the right answer 50 per cent. The candidate can only eliminate the incorrect option if he or she has read extensively about the topic or any related topic where they can infer that the given option is incorrect.

Negative Marking in IAS Prelims
There is a negative marking of one by three in the IAS prelims exam. It means that for each incorrect answer there will be a deduction of 0.66 marks from the candidate marks because each of the questions is 2 marks. The number goes in the same ratio in the General Studies paper-II where each question is 2.5 marks.
Moreover, if the candidate marks three incorrect answers and one correct answer, their score does not change because the results of the above combination is zero. But in case the candidate marks two correct questions from four. It will result in positive. It will be beneficial because each number counts in the IAS prelims exam.

UPSC IAS Prelims 2025: Marking the Answer on OMR
This is a critical part of the IAS prelims exam. The candidates should mark the answers on the OMR sheet after each page of the paper. It implies that the candidates should mark the answers on the OMR sheet after every four questions. It will help them mark the answers correctly because some candidates mark the answer in bulk which make the answer marking more prone to mistakes.
The candidates should understand that 25 to 30 per cent will go wrong so the attempt count should be such that the final score remains above the IAS Cut off.
