And if i secured 57.6% and 52% in agreegate of pcb am i eligigble from these marks in aiims and jipmer or if'nt thn after improvement am i

Hii.. The sad news for you is that you will not be eligible for AIIMS 2018 if you scored this much as t o fulfill the AIIMS MBBS 2018 eligibility criteria, the candidate must have passed in Physics, Chemistry, Biology, and English. The minimum aggregate of the marks General and OBC candidates need to have scored in Physics, Chemistry, Biology and English in their Class 12 or HSC examination must be 60%. But you will be eligible for JIPMER 2018.

Good Luck.

As you have mentioned above that your aggregate is 52% then if you are a general candidate you can only be eligible for appearing for the JIPMER examination and not the AIIMS as in AIIMS examination eligibility for appearing it is 60% above aggregate marks for general category but if you are a reserved category or physically disabled  student than you are eligible to appear for both the exam on the present aggregate score said by you because for the reserved category and physically disabled category the required criteria for aggregate marks in AIIMS is 50% so as per your said score you have 52% aggregate so if u are a reserved or physically disabled than you can appear for both exams but if not than you are eligible for only the JIPMER examination.

Hi HARSH, You will be eligible for JIPMER, as there requirement is 50% and above, But in AIIMS, its 60% and above for general category, so you won't be allowed if you belong to that
You can apply for improvement exam if you want to give AIIMS UG entrance exam

Hopefully it helps
