How to prepare for the Written Exam

Mathematics: The standard of Mathematics paper will be of Matriculation level. Total 100 questions. Therefore, a student gets about a minute plus to solve each question. It is essential for candidate to practice shortcut techniques.

General Knowledge: The syllabus for the General Knowledge paper is very vast and generic. Analyzing the past at least ten year's papers would help or else, you may focus on unnecessary, bulky details that are difficult to comprehend and remember. For example, in History one needs to drastically cut down effort on Ancient and Medieval History. Similarly in Geography one needs to cut down efforts on Human and Agricultural Geography.

The RISE Education provides students with Sample Paper and recent Current Affairs Notes prior to the Exam Day. The notes are scientifically designed on the basis of the trend analysis of 10 year’s papers of CDS so there is little chance of the questions coming out of our study material. We have a special team and website for this purpose.

So it is advisable to stick with the notes or the study material provided by the institute. It is also advisable to read an English newspaper (THE HINDU / THE TIMES OF INDIA) and any monthly magazine (such as THE CHRONICAL / PRATIYOGTA DARPAN) etc.

English: The English paper is often ignored by candidates who speak reasonably good English. They however, forget that spoken English is quite different from the Pure Application of Correct Grammar in Objective Type Questions. Those candidates who revise and practice the Basic English Grammar sufficiently can secure almost 100% marks in the grammar section, which is almost 70% of the paper. UPSC gets innovative and at times asks you to identify the wrong statements too. So be prepared for surprises.
The remaining 30% paper comprises Comprehensions, Antonyms, Synonyms, Analogy. The candidates usually spend a lot of time on this section. It is very difficult to mug up Antonyms and Synonyms; this is something that one builds over a period of time however some tricky approach can be applied on the basis of the word roots Energy-Pronunciation Relationship Trick. Similarly comprehensions which are inference based or in which you need to find out the tone of the passage and force of argument of the author can be easily understood with the help of the critical reasoning.  

General (but important) instructions about written examination

The papers in all the subjects will consist of Objective (multiple choice answers) Type questions only.

SI units will be used in the papers and Candidates should use only International form of Indian numerals (i.e. 1, 2, 3,4,5,6 etc.) while answering question papers.
