Are IISER's good colleges and are they comparable to IIT's or NIT's?? How are the placements also?

I am assuming that you want to pursue basic sciences. If you want to do engineering then there is no question at all, go for IIT.

To give you a brief account, IISERs are institutes that were set up with the idea of promoting the culture of basic sciences in India.

So, if you are passionate about doing research , you should definitely join IISER.



For curricular and extra-curricular.
After much deliberation, I would like to express my thoughts.

I ASSUME THAT YOU'RE A ASPIRING SCIENTIST, IF YOU AREN'T THEN JUST GO TO IIT.

IITs are engineering institutes, they weren't and aren't being established to create intellectual power but for highly skilled and educated man power.

IISERs are science institutes, they're goal is to create intellectual property.

The science courses in IITs aren't research oriented!!! Yes, that's true. At IISERs, the course makes you way more versatile, something which is very important in scientific research in today's day and age. IISERs are highly inter disciplinary, you'll find chemists working with biologists to make new drugs, physicists working with biologists to know better about the origin of life, mathematicians working with earth on modelling winds in a hurricane etc. IITs' science courses are application oriented and not research oriented.

One more thing, the people in IISERs are unique, yeah! They are GENUINELY curious and intelligent people. You find people seeing wind, clouds and taking about their shape and implications thereof!!! Life here is awesome. You'll never run out of new stuff to learn.

The professors at IISERs are awesome, all of them are actively doing their own research, they'll happily tell you about their research of you ask them.

Coming to jobs! IITians have good packages, but IISERites don't have a concept of so called packages instead IISERites get good PhD colleges (mostly educational institutions abroad). Again, if you're an aspiring scientist, don't worry much about pay, at the end of the day, smart people don't remain jobless.
