Hi,

Aiims in considered as one of the toughest entrance exam in the country.

The number of questions in aiims are 60 each from bio, chem n phy nd 20 from aptitude. And duration of exam is 3hr 30mins.

Coming to iiser, no of questions are 15each from phy, chem bio n maths. Duration being 3hrs.

So u can see that the questions as well as the toughness of questions are higher in aiims.

Bio in iiser is of near abt d same level as in neet

Same goes for chem n phy

And maths sec questions are appreciably good and with understanding easy to solve.

The level of AIIMS is way tougher than NEET. With regards to all the sections.

All the best
