UPSC will not make any changes to CDS 2025 syllabus, and the same will be updated in the form of an information brochure on the website, upsc.gov.in. The syllabus will be based on the Matriculation level, especially in Elementary Mathematics. The syllabus will be separate for IMA/ INA and that of OTA. The topics of English Language and General Knowledge are important and included in both the papers. Only Elementary Mathematics will be included in the question paper for IMA and INA admission. Candidates can read the article to understand the subject-wise topics included in the CDS syllabus.
CDS 2025 English Language Syllabus
The English language is included in both the IMA/ INA as well as the OTA paper. The syllabus and topics included in the English Language are as follows:
- Sentence Improvement

- True/ False Statement
CDS 2025 Elementary Mathematics Syllabus
This section is only included in the IMA and INA papers. Students preparing for the OTA paper, need not prepare for this part. Students need to cover the topics from Arithmetic, Algebra, Trigonometry, Geometry, Mensuration, and Statistics of the Matriculation level.
