6.Where can I find the solutions for the IAT (IISER) 2017 paper?

Open any question on this page. Its page shows the correct answer and, where one is available, the worked solution. A downloadable PDF of the whole paper is coming soon.

7.How should I use the IAT (IISER) 2017 paper to check my preparation?

Set a timer, attempt the 60 questions as you would in the exam, and only then open the answers. Note which subjects and chapters cost you the most marks, and revise those first using the chapter-wise practice for IAT (IISER). Repeating this with other papers shows whether the same weak spots keep coming back.

8.Will the IAT (IISER) 2017 paper help me prepare for IAT (IISER) 2027?

Yes. Every past paper shows the question styles and topics IAT (IISER) has asked before, and a solved paper gives you a realistic benchmark for speed and accuracy. Use it along with the other papers to spot the chapters that keep returning.
