• Practice With PYQ – Review previous papers from 2018 and 2022. RSSB often repeats the questions, especially in Rajasthan GK.
• Current Affairs – Focus on the last 6–8 months of Rajasthan-specific news (government schemes, sports, and awards).
• Practice the 5-Option Rule – Regularly take mock tests that include the “Option E” format to avoid silly mistakes during the actual exam.
• Educational Psychology – Don’t ignore this section in Paper-I. It often acts as a tie-breaker for high-scoring candidates.
