Expert Tips & Strategies For Scoring Good In IAS Prelims
Here are some tips and strategies for scoring desirable marks in the UPSC Prelims MCQs:
- Historically, the cutoff for marks has typically been set at around 100. To ensure a strong position, it is recommended to aim for accurately attempting approximately 60-65 questions. Avoid attempting too few or too many questions. Instead, consider adopting a balanced approach using the 50/50 strategy. Aim for around 80-85 questions, which can help you achieve a score between 107 and 108, comfortably surpassing recent trend cutoffs.
- One effective strategy for preparing for the Civil Services exam is to practice the CSAT (Civil Service Aptitude Test) throughout the year. The CSAT evaluates basic aptitude skills, so improving reading comprehension can greatly assist in daily newspaper reading and note-taking. A recommended approach is to solve one CSAT Previous Year Question each day until a few months before the examination. This consistent effort ensures coverage of the entire syllabus without overwhelming your schedule. It is also beneficial to engage in solving full-length CSAT mock papers closer to the exam date for comprehensive revision. Don’t miss out on Mitra’s IAS free initiative available on YouTube! We have a daily practice where we solve one CSAT question from Monday to Friday.
- To ensure a strong understanding of the covered concepts and topics, it is recommended to schedule regular revisions for all subjects. This will help in effectively grasping the material at hand.
- To improve your exam preparation, it is advisable to regularly attempt mock tests, solve previous year’s question papers, and Ethics test series. These practice exercises will help you understand the exam pattern better and enhance your time management skills.
- One should regularly refer to newspapers, magazines, current keynews+ from Mitra IAS, and reliable online sources to stay updated with current affairs. It is also advisable to make concise notes for easy and quick revision.
