  • Weekly mixed-chapter test: After you have completed a few chapters, take a test consisting of questions from all the chapters. This will help you find your strengths and weaknesses.

  • Note-making using charts & tables: Charts & tables are concise and help you revise quickly during the last few days of the exams.

Have a question related to AIIMS Nursing ?

Hello,

AIIMS B.Sc Nursing entrance exam ka syllabus NCERT Class 11–12 par based hota hai. Agar CBSE ya state board ne kuch chapters delete kiye hai, to bhi AIIMS apne original NCERT syllabus se hi questions pooch sakta hai. Deleted syllabus se questions aane ke chances hote hai, kyunki AIIMS board-wise reductions follow nahi karta. Isiliye aapko pura NCERT 11–12 syllabus complete padhna hoga, deleted chapters bhi.

Hope it helps!!!

Hello,

If you are getting ready for the AIIMS B.Sc. Practicing previous year question papers (PYQs) for the nursing entrance exam is among the most efficient methods to grasp the exam structure, level of difficulty, and key topics. Although AIIMS does not officially provide all its nursing previous year questions (PYQs), you can still access compiled papers and sample papers from reliable publishers, nursing entrance preparation books, or educational websites such as Arihant, MTG, or online forum like Careers360.

Hope this helps. All the best!
