Over 40 lakh students register for SBI PO every year, yet many begin preparation without understanding how fundamentally different the two stages are. Treating them as one combined exam is one of the most common — and costly — mistakes.
Prelims is a filtering round. Mains is the real battleground. Each demands a different strategy, mindset, and time investment.

Exam Structure: How Prelims and Mains Differ
SBI PO Prelims is a speed-based screening test. You get 60 minutes for 100 questions across three sections. Each section has its own timer — you cannot borrow time from one section to another.
SBI PO Mains is a comprehensive aptitude and knowledge test. It includes four objective sections totaling 200 marks, plus a 50-mark descriptive paper (letter and essay writing) conducted simultaneously.
⚠️ The descriptive paper alone separates serious candidates from the rest. Many students who crack Prelims comfortably struggle here because they never practised structured writing.
