Why CDS Current Affairs Topics Matter in the GK Paper

That is why the best way to study CDS Current Affairs Topics is to connect every news item to its basic concept. CDS GK current affairs questions are rarely about a date alone; they usually test the idea behind the news.
Which period should you cover? For CDS current affairs 2027, focus mainly on events from about April 2026 to March 2027. Major events from 2025, such as Operation Sindoor, are also worth revising because they continue to shape defence news.
