We begin our detailed paper analysis of Combined Defence Services Exam 2015 by discussing about the English Section first.


UPSC CDS Exam Analysis 2015: English Language

The Difficulty Level of CDS (l) 2015 English Paper was pretty moderate as compared to the previous years CDS papers. Some of the questions could be said as marginally tough to solve but some were pretty straight forward.

Reading Comprehension was time consuming as reported by a few candidates whereas Cloze Test, Sentence Improvement, Synonyms and Antonyms were easy to attempt. We expect the pattern to be similar this year too.

The table below tells about the number of questions from each topic in CDS (I) English Exam 2015.

 S. No.  Topic  No. of Questions
 1.  Antonyms and Synonyms  15
 2.  Spot the Error  20
 3.  Sentence Improvement  20
